Physics Question from JEE Main 2025 · 3 April, Shift 2

Using a battery, a $100 \, \text{pF}$ capacitor is charged to $60 \, \text{V}$ 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 $20 \, \text{V}$, its capacitance is : (in $\text{pF}$)
