Two small identical metal balls of radius rare at a distance a `(a lt lt r)` from each other and are charged, one with a potential `V_(1)` and the other with a potential `V_(2)`. The charges on the balls are:

A

`q_1=V_1a,q_2=V_2a`

B

`q_1=V_1r,q_2=V_2r`

C

`q_1=((V_1+V_2)/2)a,q_2=((V_1+V_2)/2)r`

D

`q_1=-r/a(rV_2-aV_1),q_2=-r/a(rV_1-aV_2)`
