PhysicsElectrostatic Potential and CapacitanceMHT CET

A capacitor of capacity C has a charge Q and stored energy is U. If the charge is increased to 2Q the stored energy will be :

Answer: (C)

Solution

, so doubling the charge makes the energy ; 2U, U/2 and U/4 are wrong. Hence the correct option is (c).
