Potential of Infinite Sheets of Charge and Conducting Slab

  1. Jan 26, 2017 #1
    1. The problem statement, all variables and given/known data
    An infinite sheet of charge is located in the y-z plane at x = 0 and has uniform charge denisity σ1 = 0.39 μC/m2. Another infinite sheet of charge with uniform charge density σ2 = -0.15 μC/m2 is located at x = c = 30 cm.. An uncharged infinite conducting slab is placed halfway in between these sheets ( i.e., between x = 13 cm and x = 17 cm). What is σa, the charge density on the surface of the conducting slab at x = 13 cm?

    2. Relevant equations

    3. The attempt at a solution
    I know the electric field in the slab is zero, but I do not know how to find the charge density on the surface of the slab in this instance. Thanks for the help in advance!

    Would it matter if the conducting slab was 2000 cm thick instead of 2 cm (with of course the same distance between b and c) ?
