Unformatted text preview: magnitudes is larger than the other, then, after contact, the balls will either both be positive or both be negative and so will repel . c) Each ball has a charge of +1 μ C. The force points away from the other charge and has a magnitude of 4 N. d) The charges that are flowing are the electrons, and so 3 μ C of electrons flow from ball 1 to ball 2. 7. a) Q = 4 "# mg tan $ d + 2 L sin ( ) = 3.01 μ C b) The Q 2 /4 πε part of the force remains the same [up to an overall minus sign] because the charge magnitudes are the same. The distance between the balls, however, is now smaller, which means that the force in the xdirection is larger in magnitude. This will pull the balls more to the sides and make a larger angle....
