    3. The figure show an edge-on view of a surface (in the middle) with some surface charge density sigma on it.
    The E-field just above the surface is E = +2z[N/C].
    Just below the surface it is E = -2z[N/C]
    What is the charge density sigma on the surface?

    By Gauss law,
    Ez*ds + (-Ez)*(-ds) = sigma*d/epsilon_0

    => sigma/(epsilon_0) = 2*Ez

    => sigma = 2*Ez*epsilon_0 = 2*2 *8.86*10^(-12) = 35.44*10^(-12) C/m^2 = 3.544 *10^(-11) C/m^2
