A point charge q is placed at a distance ‘r’ from the centre of an uncharged conducting sphere of radius R. The potential at any point on the sphere is

View answer and explanation

Correct option: B

\frac{1}{{4\pi { \in _\mathrm{o}}}}\frac{q}{r}

Option B (

\frac{1}{{4\pi { \in _\mathrm{o}}}}\frac{q}{r}

) is correct because the potential at any point on a conducting sphere is constant and equal to the potential at the surface due to the external charge.
