Question

State whether the given statement is True or False :

A small isolated conductor has a large positive charge. The electric field inside this conductor will be zero.

• A. True
• B. False

Answer 1

The correct option is A True

Electric field inside a conductor is always zero. In electrostatics, free charges in a good conductor resides only on the surface. So, free charges inside the conductor is zero. So the field in it is caused by the charges on the surface. Since charges are of same nature and distribution is uniform, the electric fields inside cancel each other.
