A capacitor is composed of two metal plates. The two plates have the dimensions L = 0.11 m and W = 0.56 m. The plates have a distance between them of d = 0.1 m, and are parallel to each other.  Part (a)  The plates are connected to a battery and charged such that the first plate has a charge of q. Write an expression for the magnitude of the electric field, |E|, halfway between the plates.  Part (b)  Input an expression for the magnitude of the electric field, |E2|, just in front of plate two.  Part (c)  If plate two has a total charge of q = -1 mC, what is its charge density, σ, in C/m2?
