A spherical metal shell A of radius R_A and a solid metal sphere B of radius R_B (< R_A) are kept far apart and each is given charge '+Q'. Now they are connected by a thin metal wire. Then

JEE Advanced 2011 Physics question

A spherical metal shell A of radius and a solid metal sphere B of radius are kept far apart and each is given charge '+Q'. Now they are connected by a thin metal wire. Then

(A)Correct
(B)Correct
(C)Correct
(D)Correct

Answer: (A),(B),(C),(D)

Solution

After connection, charge flows until both conductors are at the same potential: (they are far apart, so each potential is due to its own charge), with . (A) Inside a conductor (and inside a charged shell) the electric field is zero. True. (B) $ =
