Q2. Two charged pith balls are suspended on very light 10.7 cm strings. Each has a mass 11.0 g. In stability, the total angle between the strings is 37 degrees. Draw the free body diagram for one of the pith balls and clearly label all forces with magnitude and direction. Assume the pith balls are equally charged, what is the charge on each ball?
