A uniformly charged disk has radius 2.50 cm and carries a total
charge of 2.0×10−12 C .
What is the percent difference between the electric fields
produced by the finite disk and by a point charge with the same
charge at x = 20.0 cm?For this question I got that,
E(disk)=.44N/C and that E(point)= .45N/C.
Which gave me a percent error of 2% when I calculated it using
E(point)-E(disk)/E(point).
I don't understand why this is wrong.

Suppose you design an apparatus in which a uniformly charged disk of radius R is to produce an electric field. The field magnitude is most important along the central perpendicular axis of the disk, at a point P at distance 4.50R from the disk (see Figure (a)). Cost analysis suggests that you switch to a ring of the same outer radius R but with inner radius R/4.50 (see Figure (b)). Assume that the ring will have the same surface charge...
