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
$(1983,1 M)$
(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
Objective Questions II (One or more correct option)

Answer:
Correct Answer: 12. (a, d)
Solution:
- 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 $10 V$.
