### What is Meant by Coulomb’s Law?

According to Coulomb’s law, the force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. It acts along the line joining the two charges that are considered to be point charges. In other words, Coulomb’s law, or Coulomb’s inverse-square law, can be stated as an experimental law of physics that quantifies the amount of force between two stationary, electrically charged bodies or particles. The formula of Coulomb’s law is given as:
F = K[q1q2/d2] Here,
q1 = Charge of the first body
q2 = Charge of the second body
d = Distance between the two bodies
K = Electrostatic constant (approximately equal to 9 × 109)
