(a) Two spheres have radii a and b, and their centers are a distance d apart. Show that the capacitance of this system is
provided d is large compared with a and b. Suggestion: Because the spheres are far apart, assume the potential of each equals the sum of the potentials due to each sphere. (b) Show that as d approaches infinity, the above result reduces to that of two spherical capacitors in series.
