Two point charges of unknown magnitude and sign are placed a distance d apart.
(a) If it is possible to have E = 0 at any point not between the charges but on the line joining them? What are the necessary conditions and where is the point located?
(b) Is it possible, for any arrangement of two point charges, to find two points (neither at infinity) at which E = 0? If so, under what conditions?

Answer:
Electrostatics is a branch of physics which deals with the charges at rest. The force experienced by a charge due to another charge is known as electrostatic force. It results into attraction or repulsion of particles or objects because of their electric charges. This force is given by Coulomb's law
