You have thirty minutes to complete it. Two large, flat conducting plates, each with area A, are separated by a distance 2d, where d is much smaller than the sides. A slab with dielectric constant ε and thickness d is flush against the bottom plate. The bottom plate is grounded, and the top is at potential V0. d2d In terms of A, d, ε, and V0 find (a) the magnitude and direction of the electric field E everywhere between the plates; (b) the magnitude and direction of the displacement field D everywhere between the plates; (c) the (free) charge Q on the lower surface of the top plate; (d) the polarization charge QP on the lower surface of the slab; and (e) the capacitance C of this system. Remember to continue on, even if you are stuck on one part.
