A conducting sphere A of radius a, with charge Q, is placed concentrically inside a conducting shell B of radius b. B is earthed. C is the common centre of A and B.(a) The field at a distance r from C, where a ≤ r ≤ b, is k Q/r2.(b) The potential at a distance r from C, where a ≤ r ≤ b, is k Q/r.(c) The potential difference between A and B is kQ (1/a - 1/b).(d) The potential at a distance r from C, where a ≤ r ≤ b, is kQ (1/r - 1/b). |
