**This solution to problem 6 will NOT be given on your formula sheet**

describes charge density as a function of distance to the origin. Since the Gaussian sphere is fixed at radius we use a tilde to denote the variable of integration used to calculate the charge enclosed by the Gaussian sphere.

If the field point , the radius of the nonuniformly (but symmetrically charged sphere), then Gauss' law is:

But also,

(using the surface area of a sphere)
