Potential between two angled plates?

I have a problem involving two angled plates

L=10cm
d=1mm
$\phi$= 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/∂ $\Phi$ ^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.
