The electric potential inside a conducting sphere

Statement :-A:-Electrical potential may exist at a point where the electrical potential field is zero. Statement B:- Electrical field may exist at a point where the electircal potential is zero. Statement C:- The electric potential inside a charge conducting sphere is constant .

Electric field inside a conducting sphere is

A hollow insulated brass sphere is positively charged. The electric potential inside the sphere is

Assertion (A): Electric field inside a hollow conducting sphere is zero. Reason (R ): Charge is present on the surface of conductor.

An electrically isolated hollow (initially uncharged), conducting sphere has a small positively charged ball suspended by an insulating rod from its inside surface, see diagram This causes the inner surface of the sphere to become negatively charged. When the ball is centred in the sphere the electric field outside the conducting spehere is
