Hey I have been given the below question but am really struggling to get even the first part:
We want to find the value of the electrostatic potential in the quadrant.
where and are the standard polar co-ordinates and is a given positive real number. Assuming electrostatic potential is the solution of Laplaces equation in polar co-ordinates
The boundary conditions on are
(a) State why the differential equation with the given boundary conditions can't be solved by the method of separating variables.
The problem I am having is that I can separate the equation into to parts so I am assuming it is to do with the boundary conditions why it cannot be solved, but I don't know what aspect of the conditions effects this?
