Homework Help: Electric field of square sheet

  1. Mar 6, 2013 #1
    1. The problem statement, all variables and given/known data
    Field the electric field of a square sheet. I understand this is a simple problem, I just want to confirm I have the integral set up correctly.

    2. Relevant equations
    [tex] \vec{E} = \sigma z \int_{-a/2}^{a/2} \int_{-a/2}^{a/2} \frac{dx' \, dy'}{(x'^2 + y'^2 + z)^{3/2}} \hat{z}. [/tex]

    I just want to double check if I have set up the integral correctly.

    Looks good to me! [EDIT: In SI system there would be an overall factor of ##k = \frac{1}{4\pi\epsilon_0}##]
