| Dec 7, 2010 at 5:35 | comment | added | David Z | Electrons are so light (in the mass sense) that I can't imagine you'd be able to remove enough of them to make a measurable difference in the weight. At least not before the charge on the plate pulls more electrons in to replace the missing ones. | |
