Problem 6: A solid insulating sphere has a of radius R. Part (a) If the sphere has a uniform volume charge density of p, enter an expression for the distance (r) from the center where the electric field has a magnitude nEMax- where EMax is the electric field at the surface of the sphere. Part (b) A similar sphere has a volume charge density p = arº. Enter an expression for the distance (7) from the center where the electric field has a magnitude of nEMax-
