Question

two blocks are connected by a rope, as shown above. the masses of the blocks are 5 kg for the upper block and 10 kg for the lower block. an upward applied force of magnitude f acts on the upper block. question if the net acceleration is downward but has a magnitude less than g , then which has the larger magnitude, the force f or the tension in the rope?

Answer 1

The tension in the rope would have a larger magnitude than the applied force F when the net acceleration is downward but has a magnitude less than g.

Step-by-step explanation:

The tension in the rope must equal the weight of the supported mass. If the 5.00 kg mass is stationary, then its acceleration is zero, so the net force is zero. The only external forces acting on the mass are its weight and the tension supplied by the rope. Therefore, the magnitudes of the tension and weight must be equal, and the tension in the rope would have a larger magnitude than the applied force F.
