What is an electrostatic force? (with photo)

Rubbing a balloon against the hair forms an electrostatic force between the two objects.

Electrostatic force is the phenomenon that results from slow or stationary electrical charges. It is studied in the scientific discipline known as electrostatics by researchers who analyze electromagnetic interaction. Specifically, electrostatic force is the physical reaction that holds together the electromagnetic field created by subatomic particles such as electrons and protons. For electrostatic forces to remain cohesive, these particles need to independently maintain positive and negative charges and react to each other accordingly. According to the laws of physics, there are four fundamental forces that describe the reactions of particles, one of which is considered to be the electromagnetic force, which results in electrostatic force under certain conditions.

The electrostatic force between electrons and protons is one of the strongest forces in the universe, even more powerful than gravity. A hydrogen atom, which contains just one electron and one proton, has the fundamental force of gravity that holds them together. However, each subatomic particle can also develop electrostatic force, which becomes even stronger. In physics, the laws state that a magnitude of force must be exerted between particles that is 10 24 stronger than simple gravity. Every atom in the universe in its natural state contains a uniform amount of protons and electrons, creating a strong presence of electrostatic forces.

When two surfaces come into contact with each other, charge exchange occurs, resulting in the development of electrostatic forces. When resistance is present in one of these materials, electrostatic charges are more apparent to the observer. The resistive material retains the electrostatic charge for a long period of time until the charges are neutralized, such as with a static shock.

Coulomb’s law defines the fundamental theories about the electrostatic force of attraction within the science of electrostatics. It was established in the 1780s by a French physicist named Charles Augustin de Coulomb. He used the basic theories of electromagnetism to determine the formulas and equations that defined electromagnetic forces and electrostatics.

One of the most common examples of electrostatic force seen in everyday life occurs when someone opens a plastic package. Often, this package gets stuck to the fingers. This is due to the fact that the packaging, containing electrical resistance properties, was rubbed against other surfaces, forming an electrostatic charge. The ancient Greeks were the first to realize this concept when they researched amber. Amber has the ability to attract particles when rubbed against another material.
