A spherical cloud of charge of radius R contains a total charge +Q with a nonuniform volume charge density that varies according to the equation. p(r) =P0(1-r/R) for r is less than or equal to R and p = 0 for r>R. Determine the magnitude E of the elcetric field. Express your answer in terms of Q, R and fundamental contants. p and p0 looks like a greak letter i just use p instead.

In this case, because you are beyond the surface of the sphere you should be able to treat it like a point charge.
