Question:

(a) Determine the capacitance of an isolated conducting sphere of radius a in free space (consider an outer conductor existing at r → ∞).

(b) The sphere is to be covered with a dielectric layer of thickness d and dielectric contant r. If ∈_r = 3, find d in terms of a such that the capacitance is twice that of part (a).
