Two conducting spheres of radii `r_(1)` and `r_(2)` are equally charged. The ratio of their potentral is-

Options

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

Answer

C

Explanation

`V_(1) = (q)/(4pi epsilon_(0)r_(1)), V_(2) = (q)/(4pi epsilon_(0)r_(2)) :. (V_(1))/(V_(2)) = (r_(2))/(r_(1))`
