Coulomb's law states that the magnitude of the electrostatic force of attraction or repulsion betweentwopointchargesis directly proportional to the product of the magnitudes ofchargesand inversely proportional to the square of the distance between them.

Coulomb's law can also be referred to as Coulomb's inverse-square law. Physicist Charles-Augustin de Coulomb published the law in 1785. The law was instrumental in developing the theory of electromagnetism. Coulomb's law is experimental. It states that when charges have the same or similar sign, they repel with one another. It also states that when charges have opposite signs, they will attract one another.

This is one of the reasons we have the saying "opposites attract" because different charged signs attract each other. Coulomb's law was very influential in helping scientists bring forth advancements in the electro physics field.

Coulomb's law outlines the SI unit for charge. The scientist who invented it is popular for his immense contribution in electrical physics. He also unraveled the mysteries of charge and current, creating a very special law called the coulomb law. This law states that the charges with the similar sign repel and charges with the opposite sign attract one another. He did so with a specific force that is equal in magnitude to the product of the charges.

However, this same force is inversely proportional to the square of the distance between them. This allowed scientists to make remarkable advancements in the field of electro physics.
