Coulomb 's Law

Coulomb's Law :
The electrostatic force of interaction between two static point electric charge is directly proportional to the product of the charge, inversely proportional to the square of the distance between them and acts along the straight line joining the two charges.

If two points charge q1 and q2 separately by a distance r. Let F be the electrostatic force between these two charge. According to Coulombs law.
