The drawings show three charges that have the same magnitude but may have different signs. In all cases the distance d between the charges is the same. The magnitude of the charges is lql=8.3 C, and the distance between them is d=5.1 mm. Determine the magnitude of the net force on charge 2 for each of the three drawings.
