A capacitor 4μF charged to 50 V is connected to another capacitor of 2 μF charged to 100 V with plates of like charges connected together. The total energy before and after connection in multiples of (10^−2 J) is

Three capacitors each of capacity 4 muF are to be connected in such a way that the effective capacitance is 6 muF. This can be done by Three plates A
