Question

A positive point charge Q is placed at a point P , which is at a distance L from the centre ' C ' of an uncharged metallic ball of radius R ( L > R ) . There is a point G on the line PC, at a distance R /2 from C . Then, the electric potential at G is :-

Inside metallic ball, potential is same everywhere. V G ​ = V C ​ V C ​ = V due to Q + V due to induced charge = L K Q ​ + 0 V G ​ = V C ​ = L KQ ​
