easy

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.....$V$

A

$0$

B

$10$

C

same as at point $5\,\, cm$ away from the surface

D

same as at point $25\,\, cm$ away from the surface

Solution

Hollow metal sphere $=$ spherical shell

Electric field inside shell $= O$

Potential in constant inside thin shell

potential at surface $=$ potential at centre

$=10 \mathrm{V}$
