Electric Field due to a Charged Disk.

  1. Oct 12, 2008 #1
    1. The problem statement, all variables and given/known data
    Find the electric field due to a Charged Disk at a distance of "d" which is in the disk's axis direction. The charge has it's maximum value at disk's center and decreases towards the edges.

    I have the solution for uniformly charged disk but I can't figured it out for the situation above. Thank you.

    2. Relevant equations

    3. The attempt at a solution

    What have you tried so far? No one would help you if you don't show any attempt. Start by writing the surface charge density of the disk in terms of r, the radial distance from the disk centre to any given point on the disk.
