Two objects of unequal masses,M and m (M m),are connected by a very light cord passing over an ideal pulley of negligible mass.When released,the system accelerates,and friction is negligible.
Which one of the following free-body diagrams most realistically represents the forces acting on the two objects in the moving system?
