Electrostaticsis a branch ofphysicsthat studieselectric chargesat rest. The phenomena arise from theforces, known as electrostatic force,that electric charges exert on each other. Such forces are described byCoulomb's law.

So studying electrostatics, first of all concepts of electric charge, is introduced. It's important to know the properties of electric charge; what is meant by conservation of charge and quantization of charge? Coulombs Law describe the relationship between electrostatics force and the magnitudes of charges and the distance between the charges in question.
