A nonuniform but spherical symmetric distribution of charge has a density p given as follows: p = Po (1 - -) for Is R p = 0 for r 2 R Where Po = 3Q TLR 3 is a constant. Show that the total charge is Q b) Show that, for the region defined by r 2 R, the electric field is identical to that produced by a point charge Q. C) Obtain an expression for the electric field in the region Is R d) Compare your results in parts (b) and (c) for r = R
