Two oppositely charged but otherwise identical conducting plates of area are separated by a dielectric 1.80 mm thick, with a dielectric constant of . The resultant electric field in the dielectric is volts per meter.
a.) Compute the magnitude of the charge per unit area on the conducting plate.
b.)Compute the magnitude of the charge per unit area on the surfaces of the dielectric.
c.) Find the total electric-field energy stored in the capacitor.
