If the electric potential at a point on the surface of a hollow conducting sphere of radius $\mathrm{R}$ is $\mathrm{V}$, then the electric potential at a point which is at distance $\frac{R}{3}$ from the centre of the sphere is

• Correct answer
  A

  V
• B

  $\frac{\mathrm{V}}{3}$
• C

  $\frac{\mathrm{V}}{9}$
• D

  $3 \mathrm{~V}$

Hence, the correct answer is option: 'A'.
