Two spherical conductors each of capacity `C` are charged to potetnial `V` and `-V`. These are then conneted by means of a fine wire. The loss of energy will be

Options

A. Zero
B. `(1)/(2)CV^(2)`
C. `CV^(2)`
D. `2CV^(2)`

Answer

C

Explanation

`DeltaV = (1)/(2)(C xx C)/((C + C)) |V - (-V)|^(2) = CV^(2)`
