Consider a parallel plate capacitor composed of two metal plates separated by a dielectric of relative permittivity 5.0. The plates are separated by 0.20 mm and have area of 5.0 cm2. The potential difference between the plates is 500 V.

(a) Calculate the values of the capacitance C and the stored
charge Q. (4 marks)

(b) Determine the magnitudes of the electric field E, electric displacement D and polarization P in the dielectric material.
(3 marks)

(c) What is the free surface charge density σf on the plates?
(6 marks)

(d) What is the magnitude of the bound surface polarization charge
density on the dielectric? (2 marks)

(e) What is the bound volume polarization charge density at any
point within the dielectric? (2 marks)

I can do part: a and b I think - but c is confusing the hell out of me...
