A meter stick is balanced at its center. When you hang different mass blocks from different positions on the stick, as showu in the illustrations that follow, the stick remains balanced. Work on a whiteboard with your group: Draw all forces exerted on the stick by other objects. Remember the force exerted by Earth on the stick. Work together to devise a rule to explain this behavior (or extend the rules developed in the previons activities). Be sure that the rule is compatible with all of the experiments. 10 em 100 10 50 60 50 cm cm cm cm cm d. [ 100 g 80 g 100 g 400 g
