Question

Charge Q is distributed uniformly throughout an insulating sphere of Radius of R the magnitude of electric field at a point 2R/3 from centre is?

Answer 1

Answer:

Consider a hypothetical sphere of radii r as shown in the figure.

Total charge enclosed by hypothetical sphere is Qen=3Q

By Gauss's law, E.4πr2=ϵ0Qen=ϵ03Q

or E=4πϵ0r23Q
