A hollow metallic sphere of radius 10 cm is charged such that potential of its surface is 80 V.

Answered by admin @ 03/08/2021

Answer:

A hollow metallic sphere of radius 10 cm is charged such that potential of its surface is 80 V. Therefore it is given that r = 10 cm and v = 80 v. The potential at the centre of the sphere would be 80 V as the potential inside that sphere must be same as the potential on the surface i.e., 80 V.
