Circular Parallel Plate Capacitor

[Leitmotiv]

I haven't figured it out yet, I find it way above my understanding of phyiscs

Suppose we have two circular parallel plates or radii r, both the same radius. They have a Voltage difference of V and they are separated a distance d. What would be the Electric Field in the whole space? Actually, I'd be happy enough with the potential.

You are given the potential difference V. Knowing that, you can say that, if the potential at the negatively charged plate is V₀, the potential at the other plate is V+V₀. Now what?

What does the electric field between the plates of a capacitor look like?
