there was another answer, but i did not quite get it. it seemed to use polar coordinates or something, but i don't really understand how it set up the integral.
I have first considered an elementary ring of the charged disk
then we find electric field due to this ring at its axis from its
center at a distance z.We then used technique of
integration to find E due to whole disk.

Answer is Below.
Problem 3: Consider a disk of radius R in the xy-plane with a non-uniform surface charge density ơ(r)-ar, where a > 0 is a constant. Determine the electric field at a point z above the disk, along its axis of symmetry
The correct answer is already given. What you have to do is how
to get this answer.

1.-15 points My Notes A hollow sphere of radius a has uniform surface charge density σ and is centered at the origin. It sits inside a bigger sphere, also centered at the origin, with radius b > a and uniform surface charge density-o. Because of the spherical symmetry, the electric field will have the form E (i)-E(r)...
