##### Reference no: EM13226626

A conducting sphere in free space has a radius of a= 10cm. the capacitance of the isolated sphere is C= 4oa. now let's coat the sphere with a dielectric with fr= 3, and the thickness of the dielectric layer is d. Find d such that you exactly double the original capacitance of the sphere without the coating.
