A charge +q is placed somewhere inside t...

A charge +q is placed somewhere inside the cavity of a thick conducting spherical shell of inner radius `R_(1)` and outer radius `R_(2)`. A charge – Q is placed at a distance `r gt R_(2)` from the centre of the shell. Then the electric field in the hollow cavity-

A

Depends on both + q and Q

B

Is zero

C

Is only that due to Q

D

Is only that due to + q

Text Solution

Verified by Experts

The correct Answer is:
D
For a conductor electric field inside its cavity is only due to inside charge and not due to outside charge.
