0 A spherical shell of radius R is given charge 3q on its surface and a point charge q is placed at distance R 2 from its centre C Also there is a charge 2q placed outside the shell at a distance of 2R as shown Then SK 3q R 2 q C R 2R 2q A The magnitude of electric field at the centre C due to charges on the outer surface of shell is before closing the switch S Kq 2R B The electric potential at the centre C due to charges on the outer surface of shell is closing the switch S C The electric potential at the centre C due to charges on the outer surface of shell is closing the switch S D Charge flown through the switch into earth after closing the switch S is 5q Kq R Kq R before after
