Dielectrics and guass' law

  1. Sep 18, 2007 #1
    the answer i keep getting is wrong ... help?

    1. The problem statement, all variables and given/known data

    Two parallel plates of area 110 cm2 are given charges of equal magnitudes 9.6 × 10-7 C but opposite signs. The electric field within the dielectric material filling the space between the plates is 4.2 × 106 V/m.

    (a) Calculate the dielectric constant of the material.
    (b) Determine the magnitude of the charge induced on each dielectric surface.

    2. Relevant equations



    3. The attempt at a solution

    It is not clear but I suspect that these are non-conducting plates, in which case Gauss' law is:

    [tex]\oint E dA = E2A = \frac{Q}{k\epsilon_0}[/tex]
