Math Help - What is the solution of PDE given below?

From the above figure,

∇.(∇∅)=0

i.e.

Given boundary conditions:
(normal direction)


at grounded electrode
at upper electrode


Now how can I solve?

I have tried as follows using separation of variable-

Hope someone help me to find out the general solution of the equation mentioned above. Thank you all.....I am waiting :-w
