Electric flux density

  1. Oct 3, 2013 #1
    1. The problem statement, all variables and given/known data
    Given Xe=4.5 and E=.50 MV/m find the displacement flux density


    2. Relevant equations
    D=ε0εrE
    εr=1+Xe


    3. The attempt at a solution
    Using the equation above I get (8.85e-12)(5.5)(.50e6)=.000024338 C/m^2 which is not what the answers say they give it in nC which I can't see how they can do?

    Sorry they give it in nC/m^2

    Actually looking at it the real units are μC/m^2

    Should it be 24.338μC/m^2
