The Attempt at a Solution
I'm new to this forum and I'm not a physics guru (last time when I had touch with Physics was 3 years ago). Now I have to solve one problem in SciLab, but I can't figure out where to start. I'm asking for some help - some hints where I could start or some sketch solutions how to do this.
After the research I think I should solve two Laplace equations (in polar and cartesian coordinates) and then sum the results, but I am not sure about that. Also, I know that I need a grid N x N (where N = e.g. 60) to have nice computations.
