The correct answer is:
$50 \mathrm{~J}$
Given, capacitance, $C=10 \mathrm{mF}=10^{-2} \mathrm{~F}$
Potential, $V=100 \mathrm{~V}$
When capacitor explodes, then its whole stored potential energy is given out in the form of heat and lightning.
$$
\therefore \quad E_{\text {out }}=\frac{1}{2} C V^{2}=\frac{1}{2} \times 10^{-2} \times(100)^{2}=50 \mathrm{~J}
