A metal sphere of radius $r_{1}$ charged to a potential $V_{1}$ is then placed in a thin-walled uncharged conducting spherical shell of radius $r_{2}$ .Determine the potential acquired by the spherical shell after it has been connected for short time to a sphere by a conductor.

Solution

Since metal is an equipotential surface,when the conductor of radius $r_{1}$ is connected to conductor of radius $r_{2}$ by a conducting wire,the conductor of radius $r_{2}$ will also get charged to the potential $V_{1}$ .
