But.. the force between two point charges is  constant * charge1
*charge2/distance^2.. right?

Hmm.. but maybe you can set it up so that the charge is proportional to
voltage, then, of course, the force would be proportional to the voltage
squared.. that must be how it works..

Assume two plates.. you put a voltage on them, and one plate will have
charge = -V/C the other +V/C.. the force would be V/C*V/C... ok.. I guess it
works out..
