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`
`:.` correct graph is (A)
