A point charge `+q` is placed at the centre of a conducting spherical shell of inner radius a and outer radius b. Find the charge appearing on the inner and outer surface of the shell.

Text Solution

Verified by Experts

As the shell in neutral, if a charge `-Q` appears on the inner surfae, then a cahrge `+Q` appears on the outer surface.
Consider a Gaussian sphere, inside the shell
As, `E = 0 implies phi = 0 implies q_(enc)=0`
` q- Q = 0 implies Q =q`
