Question:
Charge is distributed within a solid sphere of radius r_0 in such a way that the charge density is a function of the radial position within the sphere of the form: ρ_E(r)=ρ_0(r/r_0).
a) If the total charge within the sphere is Q (and positive), what is the magnitude of the electric field everywhere within the sphere in terms of Q, r_0, and the radial position r ?
Express your answer in terms of the variables Q, r_0, r, and appropriate constants.
b) What is the direction of the electric field everywhere within the sphere?
Choose between
i) radially inward
OR
ii) radially outward
