You rub two 2.0-g balloons with a wool sweater. The balloons hang from 0.50-m-long very light strings. When you attach the strings together at the top, the balloons hang away from each other each string making an angle of with the vertical.

(a) Represent the situation with the force diagram for each balloon and determine the magnitudes of the forces on the diagram.

(b) What can you say about the magnitudes of the forces that the balloons exert on each other? Explain.

(c) Will the ratio of the forces that the balloons exert on each other change if the charge on one balloon is two times larger than on the other? How do you know?
