Infinite sheets of charge

  1. Feb 17, 2009 #1
    1. The problem statement, all variables and given/known data
    Two infinite sheets with surface charge density σ1 and σ2, respectively, are oriented perpendicular to the x-axis. An infinite, conducting slab of thickness a is placed between the charged sheets as shown in the figure. The conducting plate has a net charge per unit area of σC.

    σ1=8.85[tex]\mu[/tex]C/m^2
    σ2=1.5[tex]\mu[/tex]C/m^2
    σC=-3[tex]\mu[/tex]C/m^2
    a=2cm

    2. Relevant equations
    E=[tex]\sigma[/tex]/2[tex]\epsilon[/tex]0


    3. The attempt at a solution

    I figured since the magnitude of the electric field is not determined by displacement, I could just use the above equation. The only problem it that the conducting slab has different surface charge density on each side and I'm not sure how to start this. I have an exam tomorrow so any help is greatly appreciated!

    I also attached a picture of the problem.
