A hollow conducting spherical shell of radius R is charged with Q coulomb. The amount of work done for moving any charge q from the centre to the surface of the shell will be

A

`(qQ)/(4piepsilon_(0)R)`

B

zero

C

`(Qq)/(piepsilon_(0)R)`

D

`(Qq)/(2piepsilon_(0)R)`

Text Solution

Verified by Experts

The correct Answer is:
B
Potential inside the hollow conducting sphere is same as potential at the surface of the sphere `(Q)/(4piepsilon_(0)R)`.
No work is done in moving a charge on an equipotential surface.
