When I was studying a Van de Graaf generator for a physics project, I noticed
that while the generator was running, the motor sped up whenever I touched a
grounded conducting sphere to the surface of the generator. Upon removing the
conducting sphere, the motor reverted to its previous speed. Can you explain
why this is occurring?
