A phenomena in pith ball

  1. Oct 24, 2014 #1
    Hello guys,

    I'm curious in this phenomena: http://www.beaconlearningcenter.com/documents/492_01.pdf. In the second case, why don't the positive charges from pit ball move to the rod which is full of negative charges. If this happened, we would get a neutral rod and a negative pith ball.... But why didn't??

    Thank you

    This looks like a homework assignment so the question would be why do think it won't happen?

    What are negative charges in this case? And what are positive charges? Perhaps that will give you a clue as to why things happen one way and not another.
