Question: A 120 pF capacitor is charged to a potential difference 01:45 V, and the charging battery is disconnected. The capacitor is then connected in parallel

A 120 pF capacitor is charged to a potential difference 01:45 V, and the charging battery is disconnected. The capacitor is then connected in parallel with a second [initially uncharged) capacitor. If the measured potential difference across the rst capacitor drops to 13 V, what is the capacitance of this second capacitor
