Electric Field Magnitude of a Disk

A uniformly charged plastic disk has a radius of 0.220 m. At what distance from the center along the central perpendicular axis is the magnitude of the electric field equal to one-half the magnitude of the field at the center of the surface of the disk?

I don't know how to find the magnitude at the center; all I know is that somewhere in this problem requires integration. Help will be greatly appreciated.

You need to show some effort at solving the problem before someone can post a response. Recall the forum rules
On helping with questions: Any and all assistance given to homework assignments or textbook style exercises should be given only after the questioner has shown some effort in solving the problem. If no attempt is made then the questioner should be asked to provide one before any assistance is given.
