Homework Help: Question about an image charge problem

  1. Oct 21, 2016 #1
    1. The problem statement, all variables and given/known data
    . image charge problem.jpg
    With this problem, how should I set image charges so as to satisfy the same boundary condition?
    And if possible, could you let me know how can that image charge configuration be deduced?
    Thanks for reading.

    2. Relevant equations

    3. The attempt at a solution
    Well, I first put images charges just at the opposite side of the planar and spherical boundary. But I don't know what to do next.

    I guess the boundary is like this in 3D, right? :

    Do you know how to set up image charge for grounded conducting plane and for grounded conducting sphere?

    No, actually it was 2d. But that situation is confusing as well. Could you let me know how should I set image charges in that situation, if possible?
    And I know how to set the image charges for a ground conducting sphere or a plane. I know how to for a hemispherical bump attached on a plane as well.

    If you know how to set mirror charges for grounded conducting plane and sphere, this picture is enough hint for you.
