A non-uniformly charged ring is kept near an uncharged conducting solid sphere. The distance between their centres (which are on the same line normal to the plane of the ring) is 1 and their radius is R. If total charge on the ring is Q then the electric potential of the sphere will be:

Options

A. `(KQ)/R`
B. `(KQ)/l`
C. `(KQ)/(sqrt(R^(2)+l^(2)))`
D. cannot determined

Answer
