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?
