In given arrangement of the capacitors, one 3 μF capacitor has got of energy 600 μJ. Then the potential difference across 2 μF capacitor is
40 V
15 V
60 V
45 V
energy 12CV2=600 μJ 123 x10-6V2= 600x 10-6 V= 20 V P.D across AB is 60 V P.D across 2 μF is 608 x6 V =45 V in series V is inversely proportional to C
