• # question_answer A spherical conductor of radius r placed in air, is given a charge Q and potentialat the surface of a conductor is V, then the potential at a point inside the conductor and at a distance r/2 from its centre will be: A)  8 V                                         B)  4 V C)  2 V                                         D)  1 V

Potential at the surface = V Inside a conducting sphere potential at each point is same as that on the surface. $\therefore$ potential at distance R/2 = V
