About Coulomb’s Law

Coulomb’s inverse-square law, or simply Coulomb’s law, is an experimental law of physics that quantifies the amount of force between two stationary, electrically charged particles. The electric force between charged bodies at rest is conventionally called electrostatic force or Coulomb force. Wikipedia

Coulomb’s Law

The magnitude of the force between two electric charges It varies according to the size of each charge. and is inversely proportional to the square of the distance between the two charges The direction of the force acting on each other is in the straight line drawn between those pairs of charges. The force acting between charges of the same type (both positive or both negative) is repulsive and points away from each other in a direction. The straight line connecting the two charges The force acting between different types of charges (positive and negative) is attraction. and have a direction pointing toward each other in a straight line connecting the two charges.

Coulomb (Charles-Augustin de Coulomb) , French physicist Born June 14, 1736, he is widely known as the discoverer of the so-called fundamental law of electromagnetism. Coulomb’s Law, which describes the magnitude of attraction and repulsion between electric charges.

Did you know? Coulomb (C) is named for the unit of electric charge in the SI system in honor of Charles-Augustin de Coulomb where 1 C is equal to the amount of electric charge from a current of 1 A moving in 1 s.
