How to find the potential difference with constant charge

[mattz205]

Homework Statement

How would i go about finding the electric field and potential difference when there is a constant charge density between the capacitor rather than a vacuum?

Homework Equations

int E dot dA = Qencl/epsilon0
V ab = int E dot dl

The Attempt at a Solution

to be honest I am not really sure where to start this, i know how to find all this when there is a vacuum or dielectric, but what would i do to find it when there is a constant charge density?
