Two insulated metallic spheres of 3mu F ...

Two insulated metallic spheres of `3mu F` and `5 muF` capacitances are charged to `300 V` and `500 V` respectively. The energy loss, when they are connected by a wire is

A

0.375 J

B

0.0375 J

C

0.735 J

D

0.0735 J

Text Solution

Verified by Experts

The correct Answer is:
B
The loss of energy is given by,
`DeltaE=1/2((C_(1)C_(2))/(C_(1)+C_(2)))(V_(1)-V_(2))^(2)=0.0375J`
