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 €. Note that this charge configuration exhibits spherical symmetry. 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 Ē 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€0E2). -B + G
