Potential between two angled plates? I have a problem involving two angled plates Diagram http://imageshack.us/photo/my-images/841/paintzr.jpg/ L=10cm d=1mm [itex]\phi[/itex]= 1° Where I'm supposed to find the potential at any point between the plates. I recognize that I'm supposed to use the Laplace equation in cylindrical coordinates and that V is independent of z, but I end up with an equation that looks like: 0=1/ρ * ∂/∂ρ * (ρ * ∂V/∂ρ) + 1/ρ^2 * ∂^2v/∂ [itex]\Phi[/itex] ^2 (I think) and I have no idea what I'm supposed to do with it. If someone could clarify that it would be nice. Thanks in advance.
