A 60 kg person is standing on a thin, conductive disk (the person is wearing thick rubber shoes, so the person is electrically separate from the conductive disk). The disk is connected to a Van de Graaff generator (VGG) and the person places a hand on an identical, but separate VGG. If each of the VGG are activated (turned on) at the same instant and both remove electrons at a rate 500 e-/s determine

(a) (15 points) the amount of time the person would have to hold onto the VGG to float 1 mm above the conductive disk;

(b) (10 points) the amount of mass that the person will gain or lose during this time. Did the person gain or lose this mass?
