An electrostatic device consists of two concentric shells of radii a and b with surface charge densities of +Ps and -Ps, respectively. The dielectric constant of the medium between the plates is er. Note that this charge configuration exhibits spherical symmetry. E a) Find the total charge on each plate. b) Can this device be considered as a capacitor? If not, why? c) Using Gauss' law, find the electric field intensity E between the plates. d) What is the electric potential difference between the plates? e) Using E found in part (c), find the total electrostatic energy stored between the shells. (Hint: note that the energy density is 1/2€r€E). - * 6
