A hollow metal sphere of radius 5cm5 \mathrm{ cm} is charged such that the potential on its surface is 10V10 \mathrm{ V}. The potential at a distance of 2cm2 \mathrm{ cm} from the centre of the sphere is

Options

  1. Azero
  2. B10V10 \mathrm{ V}
  3. C4V4 \mathrm{ V}
  4. D10/3V10 / 3 \mathrm{ V}

Correct answer

B. 10V10 \mathrm{ V}

Step-by-step solution

Potential at any point inside the sphere = potential at the surface of the sphere =10V=10 \mathrm{ V}.
