MCQs on Electrostatics

Definition of Electrostatics

In the Coulombs Law, the Electrostatics is defined as force between charges. Basically, it is the branch of electricity in which the study of the behavior of charges. If the two bodies have same charges then repel each other and if opposite charges then attract each other. There are two type of Electrostatics laws. The laws of electrostatics are also called Coulomb Laws. All the MCQs on Electrostatics are published according to the new study syllabus for academic year 2021-22.
