Question

A hollow metal sphere is charged to a potential of 40 V. The potential at its center is ________.Group of answer choices0 V80 VDepends on the radius of the sphere-49 V40 V-80 V

Answer 1

40 V

Step-by-step explanation

Electric potential at any point inside a hollow metallic sphere is constant. Therefore, if potential at surface is 40 V, potential at centre will also be 40 V.

40V

also In a hollow sphere, with the charge on the surface of spheres, there is no charge enclosed within the sphere, since all the charges are in surface. Hence there is no electric field within the sphere.
