Electrostatics 3 Question 12

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

(1983,1M)

(a) zero

(b) 10V

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

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

Objective Questions II (One or more correct option)

Show Answer

Answer:

Correct Answer: 12. (a, d)

Solution:

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