A condenser of capacity $\displaystyle C$ is charged to a potential difference of $\displaystyle V_1$. The plates of the condenser are then connected to an ideal inductor of inductance $\displaystyle L$. The current through the inductor when the potential difference across the condenser reduces to $\displaystyle V_2$ is
Official answer
(4)
$\displaystyle \left(\frac{C\left(V_1^2-V_2^2\right)}{L}\right)^{\frac{1}{2}}$
