Electrostatic force and gravitational force

1. Two identical balls are charged to +q and +2q respectively. Draw a free body diagram for the electrostatic force on both balls when they are a distance of 1 m away from each other. Remember vectors have both size (depicted by the length of the arrow) and direction (depicted by the direction the arrow points).

2. Compare the size of the electrostatic force and gravitational force between two electrons when they are a distance, r, apart. The mass of an electron is 9.11 x 10-31 kg and the charge of an electron is 1.6 x 10-19 C. Show all work. Hint: Find the ratio of FE to FG.

3. Pith balls are small, lightweight objects that can pick up an electric charge. Suppose an experiment is performed and results show that Ball 1 attracts Ball 2. A third ball, Ball 3, is negative and repels Ball 2. What can be concluded about Ball 1? If inconclusive based on the available observations, what additional observations would be necessary in order to draw a conclusion?
