Subject: Re: Parallel Capacitor Plates: Force, Pressure and Mass (fwd)

Please define your terms.  What are Einstein's mass energy equations for masses at rest and at relativistic velocities?  Lastly, your analysis measures volume between the capacitor plates, but somehow you interpret this volume to be related to an increase mass of a capacitor plate.

Can you give a quantitative experimental example?
