Two Charge Problems

  1. Mar 7, 2004 #1
    Hey everyone! I was wondering if someone could help me with these two physics problems i have to turn in tomorrow. Here's the first:
    An ebonite rod with an excess of 6.4 X 10^8 electrons shares its charge equally with a pith ball when they touch. What is the charge on the pith ball, in coulumbs?

    Here's the second:
    How much charge does the Earth acquire if 2.5 x 10^11 electrons leave a grounded metal-leaf electroscope?

    This might help: The charge on an electron is -1.6 x 10-19 Coulombs.
