A capacitor is constructed of two concentric conducting cylindricalshells. The radius of the inner cylindrical shell is 2.29 10-3 m, and that of the outer shell is2.43 10-3 m. When the cylinders carry equal andopposite charges of magnitude 1.6010-10 C, the electric field between theplates has an average magnitude of 3.95104 V/m and is directed radially outwardfrom the inner shell to the outer shell.
a) Determine the magnitude of the potentialdifference between the cylindrical shells.
b) Determine the capacitance of this capacitor.
