Hi,
The problem is as follows:
There's a multi plate capacitor, with plates of side L, equidistant from each other, but the plates get increasingly longer as a function of horizontal distance from the first plate, starting at height A, and finishing at height B.
In other words, the first plate at x=0 has height A, and the last plate at x=B-A has height B. There are a large number of plates in this configuration. We are asked to show the capacitance of this is (ε0 L) / ln(B/A) where ε0 is epsilon naught. Has anyone got any ideas how to even start this off?
I've attached the question because my explanation of it is really bad!
Any help is much appreciated,
thanks
