Figure 23-27 shows four solid spheres, each with charge Q uniformly distributed through its volume, (a) Rank the spheres according to their volume charge density, greatest first. The figure also shows a point P for each sphere, all at the same distance from the center of the sphere. (b) Rank the spheres according to the magnitude of the electric Field they produce at point P, greatest first.
