Question
Both question (a) and (b) refer to the system of charges as 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.
a) Charge – q is distributed on the surfaces as
- – Q on the inner surface, – q on outer surface
- – Q on the inner surface, – q + Q on the outer surface
- +Q on the inner surface, –q – Q on the outer surface
- The charge –q is spread uniformly between the inner and outer surface.
The correct answer is: – Q on the inner surface, – q + Q on the outer surface
