A conducting shell of radius R carries charge `-Q`. A point charge `+Q` is placed at the centre. The electric field E varies with distance `r` (from the centre of the shell) as

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
A
Using Gauss theorem
`E=(1)/(4pi epsilon_(0))*(Q)/(r^(2)) " for "r le R`
and E = o for `r ge R`
`:.` The correct graph is (a).
