A solid conducting sphere of radius a is enclosed in a concentric shell of radius `b gt a`. The charge on the inner sphere is `3muC` and on the conducting shell is `-10muC`. The potential difference between the conductors is V. If `+10muC` additional charge is given to the outer shell, the new potential difference is

A

V

B

V/2

C

2V

D

zero

Text Solution

Verified by Experts

The correct Answer is:
A
The potential difference between and the two conductors
`DeltaV=(Q_(1))/(4piepsilon_(0))(1/a-1/b)`
is independent of the charge on the outer shell.
`:.` potential difference will remain same.
