An ideal capacitor of capacitance $\displaystyle 0.2 \mu \mathrm{~F}$ is charged to a potential difference of $\displaystyle 10$ V. The charging battery is then disconnected. The capacitor is then connected to an ideal inductor of self inductance $\displaystyle 0.5$ mH. The current at a time when the potential difference across the capacitor is $\displaystyle 5$ V, is :
