Quizplus · Accepted Answer

According to the diagram, Cube 1 is attracting Cube 2 and repelling Cube 3. Therefore, Cube 2 and Cube 3 are going to have equal and opposite forces acting on each other. This means that the forces of Cube 2 on 3 and Cube 3 on 2 should be symmetrical, as shown in Choice II. Choices I, III, IV, and V do not show symmetrical forces.
