Electrostatics 3 Question 12

12. A hollow metal sphere of radius 5 cm is charged such that the potential on its surface is 10 V. The potential at the centre of the sphere is

(1983,1M)

(a) zero

(b) 10 V

(c) same as at a point 5 cm away from the surface

(d) same as at a point 25 cm away from the surface

Show Answer

Answer:

Correct Answer: 12. (b)

Solution:

  1. Electric potential at any point inside a hollow metallic sphere is constant. Therefore, if potential at surface is 10 V, potential at centre will also be 10 V.
