A certain capacitor is charged to a potential difference V. If you wish to increase its stored energy by 77%, by what percentage should you increase V

33%

Explanation:

Energy stored in a capacitor (U) =

The capacitance is constant. Hence,

V2/V1 =

If U1 = 1, then U2 is an increase of 77% (0.77), hence U2 = 1.77

V2/V1 =

V2/V1 = 1.33

Hence, the v of the capacitor should be increased by 33% in order to increase its stored energy by 77%.
