Electroscope question

  1. Feb 5, 2012 #1
    Question is posted in paint doc... I think it is C, because polarization will occur sending neg charge down to the leaves making them repel. is this correct?

    The answer C is not correct unless the charge on the negative rod is significantly greater in magnitude than the charge on the positive rod.

    The explanation regarding polarization is somewhat correct, but remember, the leaves have a pre-existing positive charge.

    I believe it would have to be A then. I think the leaves will still have a slight repulsion but not as much....
