3. A cylindrical capacitor consists of a cylinder of radius R, surrounded by a coaxial cylinder shell of inner radius R.(see Fig.3 below, R. > R,). Both cylinders have length L which we assume is much greater than the separation of the cylinders R. – R,, so that we can neglect any end effects. Now the capacitor is charged (by connecting it to a battery) so that the inner cylinder carries a charge +Q and the other one a charge -Q. Note that charges are only distributed over the outer surface of the inner cylinder and the inner surface of the outer cylinder, because of electrostatic equilibrium for these metal conductors; as a result, the electrostatic field only exists in the empty space between two cylinders. Determine: (a). The electric field E(r) as a function of the radius r measured with respect to the central axis of the cylinders. [hint: draw a proper Gaussian surface and then use Gauss's law.] (b).
