A small conducting spherical shell with inner radius a and outer radius b is concentric with a larger conducting spherical shell with inner radius c and outer radius d. The inner shell has total charge +2q, and the outer shell has charge +4q. (K=(1)/(4piepsilon_(0))) Find the electric field in terms of q and the distance r from the common centre of the two shells for (i) b lt r lt c (ii) c lt r lt d |
