Calculating Electrostatic force between parallel plates

  1. Feb 10, 2012 #1
    Hi All

    I'm a professional Electronics Engineer and very much an amateur physicist. I'm trying to find the force exerted between 2 parallel plates for a given plate voltage, separation, and plate area.

    I've found plenty of wiki's, google pages etc etc of force between 2 point charges, however I'm looking specifically for the force between 2 plates. (I need to find out how much voltage is required to separate 2 plates of insulated metal against the force of gravity)

    Can anyone point me in the right direction? would be much obliged! I'll even answer any electronics questions for the right answer :-)
