Electric and gravitational forces are two of the four fundamental forces in nature, the other two being weak force and strong force. While both electric and gravitational forces are essential to understanding the structure and behaviour of the universe, they operate on vastly different scales. Gravitational forces are responsible for the formation of large-scale structures in the universe, such as planets, stars, and galaxies, while electric forces play a crucial role in the interactions between particles on a smaller scale, such as in the formation of atoms and molecules. Despite the astronomical magnitude of gravitational forces, electric forces are considered to be much stronger, even at very small ranges. This is because electric forces can be either attractive or repulsive, while gravitational forces are always attractive.

Electric forces are stronger than gravity in small ranges
Electric forces are much stronger than gravity in small ranges. In fact, electricity is almost a trillion-trillion-trillion-trillion-trillion times stronger than gravity. The gravitational force is so weak that it is surprising that we have noticed it at all.
To understand this, let's consider the forces at play in everyday objects like apples. A medium-sized apple weighs about 100 grams, and the force of gravity between the apple and the Earth is about 1 newton. This is the downward force you feel when holding an apple, and it is not too difficult to lift an apple off a table. Now, consider the electric force between two apples. Since the number of positive and negative charges in both apples is equal, the electric force between them is 0. However, if we charge one apple to +1 coulomb and the other to -1 coulomb, the electric force between them becomes significant compared to the gravitational force.
This principle can be extended to the atomic scale. Almost every negative charge (electron) in the universe is nestled up close to a positive charge (the nucleus of an atom), equalizing the electric force. This is why we are usually unaware of electric forces in everyday life. However, with a very small portion of an object's electrical charges out of balance, you can easily pick up another electrically charged object, demonstrating the dominance of electric forces over gravity at small scales.
The difference in strength between electric and gravitational forces is also evident in the fundamental forces of nature. There are four fundamental forces: gravitation, electromagnetic, weak force, and strong force. The electromagnetic force, which includes electric forces, is incredibly strong compared to gravity. For example, a small refrigerator magnet can easily overcome the gravitational pull of the entire Earth.
In summary, electric forces are much stronger than gravity in small ranges due to the inherent weakness of gravity and the cancelling out of positive and negative charges at larger scales.

Gravitational forces are responsible for the formation of large-scale objects in the universe
The electric force is much stronger than the gravitational force. In fact, electricity is almost a trillion-trillion-trillion-trillion-trillion times stronger than gravity. However, despite being the weakest force, gravity plays a crucial role in the formation and structure of large-scale objects in the universe, such as planets, stars, and galaxies.
Gravity is a long-range force that acts across infinite distances and is responsible for pulling entities with mass together to form these large-scale structures. The early universe was composed mostly of hydrogen atoms, which clustered around dark matter due to gravity. Over time, these clouds of hydrogen gas grew denser and eventually collapsed under their own gravitational pull, leading to the formation of the first stars and galaxies. Gravity also forces protons to fuse together, building more complex elements essential for the creation of planets that contain the building blocks for life.
The strength of gravity depends on the masses of the objects involved and the distance between them. According to the general theory of relativity, gravity can be understood as bends and curves in spacetime caused by objects with mass, which attract other objects towards them. This attractive force is what allows galaxies, stars, and planets to form and maintain their structure.
While electric forces are much stronger than gravitational forces, they primarily come into play on smaller scales, such as in the formation of atoms and molecules. Electric forces are responsible for keeping electrons in orbit around atomic nuclei and enabling chemical compounds to form. In contrast, gravity operates on a larger scale, shaping the universe by forming galaxies, stars, and planets.

Electric forces play a role in the interactions between particles on a smaller scale
Electric forces are much stronger than gravitational forces. While the latter is responsible for the formation and structure of large-scale objects in the universe, such as planets, stars, and galaxies, electric forces play a crucial role in the interactions between particles on a smaller scale.
Electric forces are responsible for the formation of atoms and molecules. They cause an attraction between particles with opposite charges and repulsion between particles with the same charge. This is known as Coulomb's law, which states that the magnitude of the electric force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. In other words, as the distance between ions increases, the force of attraction and binding energy approach zero, and ionic bonding becomes less favorable. Conversely, as the magnitude of opposing charges increases, energy increases, and ionic bonding becomes more favorable.
The electromagnetic force is involved in all forms of chemical phenomena and is essential for understanding atomic and intermolecular interactions. It explains how materials carry momentum despite being composed of individual particles and empty space. For example, the forces we experience when pushing or pulling ordinary material objects result from intermolecular forces between individual molecules in our bodies and in the objects.
Additionally, electric forces can be used to understand the magnetic field generated by moving charges, as described by Coulomb's law and Ampère's force law. The Lorentz force law describes microscopic charged particles, and the electromagnetic force is responsible for many of the chemical and physical phenomena observed in daily life. For instance, the electrostatic attraction between atomic nuclei and their electrons holds atoms together, and electric forces allow different atoms to combine into molecules, including macromolecules such as proteins that form the basis of life.

The gravitational force is always attractive and cumulative
The gravitational force is extremely weak compared to the electric force. This is because the gravitational force is so weak that it is surprising that we have noticed it at all. The electric force is unimaginably greater than the force of gravity. In fact, electricity is almost a trillion-trillion-trillion-trillion-trillion times stronger than gravity.
The electric force dominates on smaller scales, such as in the formation of atoms and molecules, while gravity dominates large-scale attractions. This is because the gravitational force is always attractive, and therefore cumulative. The first "attractive" force in the universe was electromagnetism. However, gravity constantly pulled the dust together, and it is only once it began to clump in large lumps that the attractive force started to have noticeable effects at a small scale.
In Newtonian physics, the gravitational force between two bodies is the sum of the minuscule gravitational forces between each and every particle making up the two bodies. This is why the gravitational force is cumulative. However, it would be very cumbersome to calculate the gravitational force in this way.

Electric forces come in attractive and repelling varieties
Electric forces are incredibly stronger than gravitational forces. In fact, electricity is almost a trillion-trillion-trillion-trillion-trillion times stronger than gravity. The gravitational force is so weak that it is surprising that we have noticed it at all.
The electric force is also different from the gravitational force because it works on a smaller scale, such as in the formation of atoms and molecules. Gravitational forces, on the other hand, are responsible for the formation and structure of large-scale objects in the universe, such as planets, stars, and galaxies.
The attractive and repulsive nature of electric forces can be seen in the movement of electrons. Electrons are pushed through wires as they repel each other, forcing them down the wire. However, an electron and a positron will attract each other. This can be seen in the work of Robert A. Millikan, who used tiny electrically-charged oil drops to balance the downward pull of gravity with an upward electrical force.
The fact that electric forces can be both attractive and repulsive is an important distinction from gravitational forces, which are always attractive. This difference has significant implications for our understanding of the structure and behavior of the universe.
