A point charge `Q` is located at the centre of a hollow spherical conductor having inner radius as `R_(1)` and outer radius `R_(2)`. The conductor being uncharged initially. The potential at the inner surface will be

Options

A. `KQ[(1)/(R_(1))+(1)/(R_(2))]`
B. `KQ[(1)/(R_(1))-(1)/(R_(2))]`
C. `KQ[(1)/(R_(2))-(1)/(R_(1))]`
D. none of these

Explanation

Find the charge distribution on the inner and outer surface of the sphere applying gauss's law.
