A series combination of $\displaystyle n_1$ capacitors, each of value $\displaystyle \mathrm{C}_1$, is charged by a source of potential difference 4V. When another parallel combination of $\displaystyle n_2$ capacitors, each of value $\displaystyle \mathrm{C}_2$, is charged by a source of potential difference $\displaystyle V$, it has the same (total) energy stored in it, as the first combination has. The value of $\displaystyle \mathrm{C}_2$, in terms of $\displaystyle \mathrm{C}_1$, is then :
Official answer
(1)
$\displaystyle \frac{16 \mathrm{C}_1}{n_1 n_2}$
