I invented this problem you don't have to do it, take 2 wrinkled spheres of opposite charge rhocharge2 and equal radius, volumerho1 of the spheres=$\displaystyle 1+\frac{1}{2}sin(m\pi) sin(n\phi), m=6, n=5$ the spheres overlap in a region and the vector between the centers of the spheres is d. what is the electrical field between the 2 spheres. I'm curious if there are more Gaussian surfaces than spheres, cylinders, boxes....
