Uniformly Charged Disk above a grounded conducting plane

  1. Oct 18, 2015 #1
    A uniformly charged disk has radius R. It was a charge density gif.gif and is located above the conducting plane at a distance a. The disk is parallel to the conducting plane. Find the electrostatic potential at (0,0,z) in the region above the plane. The conducting plane is grounded

    Use the homework template - your post will most likely be deleted.
    Draw out the disk and pick a point on the z axis where you want to measure the E field. Then resolve the E field into its components (some will cancell) Then use coulombs law and think how you can find Q of the ring. (Think linear charge density)
