I Rubber ball and electrons

  1. Sep 7, 2016 #1
    A friend of mine posed a question; if you take a rubber ball and bombard it with electrons, what would happen?

    I posited that some of the electrons would likely stay on the surface of the ball, giving it a negative charge. I then suggested that if under the "right" conditions you may be able to have photons or some other kind of electromagnetic radiation emitted.

    Am I totally off or was there some truth to what I was saying?

    You could certainly induce a negative surface charge.
    The EM is also true, if only because "some kind of EM radiation" covers such a wide range.
    By the time you got "real" EM out of the thing, you would be destroying the rubber.

    ... now switch to a steel ball and you can get some significant x-rays.

    BTW: You should do these experiments in a vacuum.
