Question

A hollow metal sphere of radius 5 cm is charged such that potential at its surface is 10 V . The potential at the centre of the sphere is (A) zero volt (B) 10 V (C) same as at point 5 cm away from the surface (D) same as at point 10 cm away from the surface

Tardigrade Admin · Accepted Answer

Electric field inside a spherical charge is everywhere zero, hence, inside a spherical charge the potential at all points is the same and its value is equal to that on the surface.

∴

Potential at surface

= 10 V .

Q. A hollow metal sphere of radius 5cm is charged such that potential at its surface is 10V . The potential at the centre of the sphere is

zero volt

10 V

same as at point 5 cm away from the surface

same as at point 10 cm away from the surface

Electric field inside a spherical charge is everywhere zero, hence, inside a spherical charge the potential at all points is the same and its value is equal to that on the surface. ∴ Potential at surface =10V.

Q. A hollow metal sphere of radius $5 c m$ is charged such that potential at its surface is $10 V$ . The potential at the centre of the sphere is

Electric field inside a spherical charge is everywhere zero, hence, inside a spherical charge the potential at all points is the same and its value is equal to that on the surface.
$∴$ Potential at surface $= 10 V .$
