6. In both cases, a massless rod is supported by a fulcrum, and a 200-kg hanging mass is suspended from the left end
of the rod by a cable. A downward force F keeps the rod at rest. The rod in case A is 50 em long, and the rod in
case B is 40 cm long. (Each rod is marked at 10-centimeter intervals.)
Will the magnitude of the vertical force F exerted on the rod be (a) greater in case A. (b) greater in case B, or (c)
the same in both cases?
