Coulomb's Law

 What is 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 distance between them. It act as along the line joining the two charges considered to be point charges.

Coulomb's Law Formula 

`F=\frac1{4πε_0}\.\frac{q_1q_2}{r^2}`

where, ` \varepsilon_0` is permitivity in free space
