Using a battery, a $\displaystyle 100$ pF capacitor is charged to $\displaystyle 60$ V and then the battery is removed. After that, a second uncharged capacitor is connected to the first capacitor in parallel. If the final voltage across the second capacitor is $\displaystyle 20$ V , its capacitance is: (in pF )
Official answer
From NTA’s final answer key for this paper.
