A point charge q is placed inside a conducting spherical shell of inner radius 2R and outer radius 3R at a distance of R fro the centre of the shell. The electric potential at the centre of shell will (potential at infinity is zero).

A

`1/(4piepsilon_(0)) q/(2R)`

B

`1/(4piepsilon_(0)) (4q)/(3R)`

C

`1/(4piepsilon_(0)) (5q)/(6R)`

D

`1/(4piepsilon_(0)) (2q)/(3R)`

Text Solution

Verified by Experts

The correct Answer is:
C
`V_(c)=1/(4piepsilon_(0))[1/R-1/(2R)+1/(3R)]=1/(4piepsilon_(0))((5q)/(6R))`
