Question

the solid sphere of radius 20cm is charged uniformly the distance from the surface of sphere where the electrostatic potentialis half of that of the centre is
​

Answer 1

Answer:

A solid sphere of radius r is charged uniformly at what distance from its surface is the electrostatic potential is half the potential at its Centre

A solid sphere of radius R has charge q uniformly distributed over its volume. The distance from it surfce at which the electrostatic potential is equal to half of the potential at the centre is. Distance from surface is x-R=R/
