    A parallel plate capacitor of capacitance 'C' is connected to a battery and charged to a potential 'V'. Another capacitor of capacitance '3C3C' is charged to a potential '3V3V'. The charging battery is then disconnected and both the capacitors are connected in parallel to each other such that positive terminal of one is connected to negative terminal of the other. The final energy of the configuration is

    Two circular plates each of radius 'rr' are kept parallel to each other distance 'dd' apart. The capacitance of the capacitor formed is 'C1C_1'. If the radius of each of the plates is increased to 3\sqrt{3} times the earlier radius and their distance of separation decreased to half the initial value, the capacitance now becomes 'C2C_2'. The ratio C1:C2C_1 : C_2 is
