An ideal capacitor, with initial charge $,$ is connected in series to an ideal inductor to form a series LC circuit. At $=0$ s$,$ the capacitor is fully charged and the current through the circuit is $0\mathrm{.}0$ A$.$ What is the magnitude of the potential difference across the inductor at $=0$ s$?$ A$)0\mathrm{.}0$ V B$)$ C$)2$ D$)$ E$)2$
