Shells Losing Energy !

Electricity and Magnetism Level 4

An arrangement of two concentric conducting spherical shells charged initially such that the inner shell (radius = \(a\)) carries a net charge of \(+Q\) while outer shell (radius \(b\)) carries net charge \(0\). If the switch "\(S\)" is closed, how much electrostatic potential energy would the system lose?

\[\frac{Q^2}{4 \pi \epsilon_0 a}\] \[\frac{Q^2 (b-a)}{4 \pi \epsilon_0 ab}\] None of These \[\frac{Q^2}{4 \pi \epsilon_0 b}\] \[\frac{Q^2}{8 \pi \epsilon_0 a}\] \[\frac{Q^2}{8 \pi \epsilon_0 b}\]
