1. Electrostatics Austin, Science Teacher Electrostatics is the branch of Physics, which deals with static electric charges or charges at rest. In this chapter, we shall study the basic phenomena about static electric charges. The charges in an electrostatic field are analogous to masses in a gravitational field. These charges have forces acting on them and hence possess potential energy. The ideas are widely used in many branches of electricity and in the theory of From: Rajesh Subramaniam, XII B 12th August 2017, 8.12 p.m. Sir, What is the theory of atom? ...
