A spherical conductor of radius 0.12 m has a charge of `1.6xx10^(-7)`C distributed uniformly on its surface, what is the electric potential?
(a) inside the sphere?
(b) Just outisde the sphere?
(c) At a point 0.18 m from the centre of the sphere?

Explanation

(a) Zero
(b) `10^(5) NC^(-1)`
( c) `4.4 xx 10^(4) NC^(-1)`
