Question

12. A point charge +Q is placed at the centre O of an uncharged hollow spherical conductor of inner radius ‘a’ and outer radius ‘b’. Find the following:
(a) The magnitude and sign of the charge induced on the inner and outer surface of the conducting shell.
(b) The magnitude of electric field vector at a distance (i) r = , and (ii) r = 2b, from the centre of the shell.

Answer 1

Answer:

as the electricity field inside a conductor is zero using gauss law inner surface of the shell = -q and charge on the outer surface of the shell = +q
