  1. The electrostatic force between two like ions that are separated by a distance of 5.0 x 10-10m is 3.7 x 10-9N.
    1. What is the charge on each ion?
    2. Each ion has a mass of 4.68 x 10-26 kg. What is the magnitude of the gravitational force between the two ions?
    3. Compare the magnitude of the gravitational and electric forces.
  2. Three point charges of +4.0 x 10-6 C are fixed at the corners of an equilateral triangle of side 10 cm. What force (magnitude and direction) acts on a typical charge?
