electrostatics - Capacitance of two non parallel plates


What is the formula for capacitance of two non parallel plates at an angle with each other?If the plates were parallel then the value can be calculated as (PermittivityX area of one plate)/distance between them.But what happens in case the plates are tilted at an angle?The question came to mind while trying to understand electrostatic separator.What would be the derivation of the formula for capacitance of two non parallel plates placed at an angle?


I did get a method from http://www.davidpublishing.com/davidpublishing/upfile/12/15/2011/2011121573197833.pdf Equation 6 from the above link above helps but it is independent of the length of the plates which doesn't seem likely.

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
