How to find the potential difference with constant charge

  1. Jun 24, 2015 #1
    1. The problem statement, all variables and given/known data
    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?

    2. Relevant equations
    int E dot dA = Qencl/epsilon0
    V ab = int E dot dl

    3. The attempt at a solution
    to be honest im 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?
