(A) The energy stored in a capacitor is given by the formula $U = \frac{1}{2} CV^2$.Given:Capacitance $C = 4 \times 10^{-6} \ F$Potential difference $V = 100 \ V$Substituting the values into the formula:$U = \frac{1}{2} \times (4 \times 10^{-6}) \times (100)^2$$U = \frac{1}{2} \times 4 \times 10^{-6} \times 10000$$U = 2 \times 10^{-6} \times 10^4$$U = 2 \times 10^{-2} \ J$$U = 0.02 \ J$Therefore,the energy required to discharge the capacitor is $0.02 \ J$.
