Question

A charge +q is placed somewhere inside the cavity of a thick conducting spherical shell of inner radius R1 and outer radius R 2. A charge +Q is placed at a distance r > 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

Following Gauss’ law, electric field inside cavity is proportional to enclosed charge + q only.

Q. 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 $r > R_{2}$ from the centre of the shell. Then the electric field in the hollow cavity

depends on both + q and + Q

is zero

is only that due to + Q

is only that due to + q

Following Gauss’ law, electric field inside cavity is proportional to enclosed charge $+ q$ only.
