Question

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. (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

Hollow metal sphere = spherical shell Electric field inside shell =0 B Potential in constant inside thin shell potential at surface = potential at centre =10 V

Q. 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.

zero

10 V

same as at a point 5 cm away from the surface

same as at a point 25 cm away from the surface

Hollow metal sphere $=$ spherical shell
Electric field inside shell $= 0$
${B}$ Potential in constant inside thin shell
potential at surface $=$ potential at centre $= 10 V$
