Question

A hollow metal sphere of radius 5 cm is charged such that
the potential on its surface is 10 V. The potential at a distance
of 2 cm from the centre of the sphere is
(a) zero (b) 10 V (c) 4 V (d) 10/3 V

Answer 1

Answer:

b) 10V

Please mark me the brainliest and follow me

Answer 2

Answer:

b) 10 V

Explanation:

Hollow metal sphere = spherical shell

Electric field inside shell = 0

{B} Potential in constant inside thin shell

potential at surface = potential at centre  

=10V.
