Lever Balance Displacement Calculation

[jonlg_uk]

Hello I am trying to design a force balance lever system. Basically the initial state will in a force balance equilibrium. That is, there will be a mass m placed onto of the capacitor plate to keep the lever balanced. I will then ramp the voltage of the capacitor up, causing a force of attraction, Fatt, creating by the plates attracting one another.

I want to know an equation for finding the distance displacement for the other mass M? How much will its height from the floor vary with increasing force of attraction, Fatt?

I thank you all in advance

N.B I have already figured out how to calculate the Faa, so there is no need to worry about that.

Basically all this is,is a old fashioned weighing scales balance and I want to know how you calculate the displacement
