point charge q is placed at distance R 2 from its centre C Also there is a charge 2q 1 K 4ca E placed outside the shell at a distance of 2R as shown Then K R 2 9 3q C 2R 2q 48 A the magnitude of electric field at the centre C due to charges on the outer surface of Ka shell is before closing the switch S 2R B the electric potential at the centre C due to charges on the outer surface of shell is Kq before closing the switch S R C the electric potential at the centre C due to charges on the outer surface of shell is Kq after closing the switch S R
