Question

Capacitance of an isolated conducting sphere of radius R₁ becomes n times when it is enclosed by a concentric conducting sphere of radius R₂ connected to earth. The ratio of their radii $\left( {{{{R_2}} \over {{R_1}}}} \right)$ is :

${n \over {n - 1}}$

${{2n} \over {2n + 1}}$

${{n + 1} \over n}$

${{2n + 1} \over n}$
