Q)
Two concentric shells of radii d and 2d respectively are placed far away from a parallel plate capacitor. Each plate of the capacitor is a square of side d and the separation between the plates is $\large\frac{d}{4 \pi}$. The charge on the plates are q and -q. Then the keys $K_1$ and $K_2$ are closed, find the charges on the shells and electric potential energy left in the parallel plate capacitor in equilibrium.
