Consider two charged metallic spheres `S_(1)`, and `S_(2)`, of radii `R_(1)`, and `R_(2)` respectively. The electric fields `E_(1)`, (on `S_(1)`,) and `E_(2)`, (on `S_(2)`) the ir surfaces are such that `E_(1)//E_(2) = R_(1)//R_(2)`. Then the ratio `V_(1)`(on `S_(1)`)/`V_(2)` (on `S_(2)`) of the f electrostatic protentilas on ecah sphere is
A. `(R_(1)//R_(2))^(2)`
B. `((R_(1))/(R_(2)))^(3)`
C. `(R_(2)//R_(1))`
D. `R_(1)//R_(2)`
