Hello people ~
A hollow metal sphere of radius 5 cm is charged so that the potential on its surface is 10 V. The potential at the centre of the sphere is
(a) 0 V
(b) 10 V
(c) Same as at point 5 cm away from the surface
(d) Same as at point 25 cm away from the surface
​

Respuesta :

Answer:

10V

Explanation:

Hollow sphere means two spherical surfaces inside

So charge on the surface =Charge at any point in sphere i.e voltage remains constant.

So

potential at centre=Potential at surface=10V

Option B is correct
