A disk of radius 248 cm has a surface charge density of 503

Question

Problem: A disk of radius 2.48 cm has a surface charge density of 5.03 μC/m² on its upper face.

Part A: What is the magnitude of the electric field produced by the disk at a point on its central axis at distance z = 10.0 cm from the disk?

Would you be able to include the how you do it steps and equation and how to follow it thank you!!
