Shown in the figure a spherical shell with an inner radius ′a′ and an outer radius ′b′ is made of conducting material. A point charge +Q is placed at the centre of the spherical shell and a total charge -q is placed on the shell. Charge -q is distributed on the surfaces as :
Options
A.-Q om the inner surface, -q, on outer surface
B.-Q om the inner surface, -q + Q on the outer surface
C.+Q om the inner surface, -q - Q on the outer surface
D.The charge -q is spread uniformly between the inner and outer surface
Solution
Due to the induction, the opposite nature nature of charge is induced at near by surface.
