A capacitor `C` is charged to a potential difference `V` and battery is disconnected. Now if the capacitor plates are brough close slowely by some distance:

A 100pF capacitor is charged to a potential difference of 80.0V and the charging battery is disconnected. The capacitor is then connected in parallel with a second capacitor. If the potential difference across the first capacitor drops to 35.0 V what is the capacitance of this second capacitor?

A capacitor of capacity C is charged to a potential difference V and another capacitor of capacity 2C is charged to a potential difference 4V . The charged batteries are disconnected and the two capacitors are connected with reverse polarity (i.e. positive plate of first capacitor is connected to negative plate of second capacitor). The heat produced during the redistribution of charge between the capacitors will be
