# Electric field of square sheet

## Homework Statement

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.

## Homework Equations

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

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