A thin spherical conducting shell of radius R has a charge q. Another charge Q is placed at the centre of the shell. The electrostatic potential at a point P a distance `R/2` from the centre of the shell is

A

`((q+Q))/(4pi epsilon_(0)) (2)/(R )`

B

`(2Q)/(4pi epsilon_(0)R)`

C

`(2Q)/(4pi epsilon_(0)R)-(2q)/(4pi epsilon_(0)R)`

D

`(2Q)/(4pi epsilon_(0)R) +(q)/(4pi epsilon_(0)R)`

Text Solution

Verified by Experts

The correct Answer is:
D

`V_(P)=(kq)/(R ) +(kQ)/(R//2) =(kq)/(R ) +(2kQ)/(R ) =(k)/(R ) (q+2Q)`
