A spherical capacitor consists of a spherical conducting shell of radius b and charge − Q concentric with a smaller conducting sphere of radius a and charge Q. (a) Find the capacitance of this device. (b) Show that as the radiusb of the outer sphere approaches infinity, the capacitance approaches the value a/ ke = 4πϵ0a.
