(a)Determine the capacitance of an isolated conducting sphere of radius a in free space (Consider an outer conductor existing at r -> infinity).
(b) The sphere is to be covered with a dielectric layer of thickness d and have a dielectric constant of εr. If εr= 3, find d in terms if a such that the capacitance found is 2 times that of part a.
