How Do You Calculate the Electric Field at a Point Above a Charged Square?

[clanish]

Homework Statement

Discuss the electric field at a point P positioned z= 2cm vertically above the center of a horizontal square surface of side length a = 5 cm that carries a uniform charge of Q = 10^-8

1. Use an integral to write an expression for the vertical component of the elrctric field at point P (answer should include a double integral/surface integral).
