Two concentric shells have radii R and 2R charges q4 and q and potentials 2V and 3 2 V respectively if potential at infinity is zero Now shell B is earthed and let charges on them become q and q B Then A 94 9B 1 2 d A 9 B 1 B C potential of A after earthing becomes 3 2 V DY potential difference between A and B after earthing becomes V 2
