1. Make note of the sign of the charge on each charge separator. Compare the magnitude of the charge on each.

2. From your answer to question 1, account for the shape of the graph in terms of the transfer of charged particles between the charge separators. Account for the features of the graph when each of the charge separators were in the pail separately and when they were in the pail together.
