In electrostatics, charge is always at rest. when charge is at rest ,it is source of an electric field.

Charge:- It is excess or defficiency of electrons on a body.

Method Of Charging:- 1- By Induction, 2- By Conduction, 3- By Friction.

Quantization Of Charge:- Only an integral number of electrons can be transferred from one body to another  means; Q = ±ne where, n = an integer & e = charge on an eclectron.

Coulomb's Law:- According to this las if q1 and q2 are two charges seperated by distance r then electrostatic force between them is given by

                            F = K |Q1|X|Q2|/rxr ; k = Constant.
