Two containers of sand are arranged like the block as shown in figure. The containers alone have negligible mass; the sand in these containers has a total mass Mtot; the sand in the hanging container H has mass m.To measure the magnitude of the acceleration of the system, a large number of experiments have been carried out where m varies from experiment to experiment but Mtot does not; that is, sand is shifted between the containers before each trial.Which of the curves gives the tension in the connecting cord (the vertical axis is for tension)?

Answer» Two containers of sand are arranged like the block as shown in figure. The containers alone have negligible mass; the sand in these containers has a total mass $M_{t o t}$ ; the sand in the hanging container $H$ has mass $m$ . To measure the magnitude of the acceleration of the system, a large number of experiments have been carried out where $m$ varies from experiment to experiment but $M_{t o t}$ does not; that is, sand is shifted between the containers before each trial. Which of the curves gives the tension in the connecting cord (the vertical axis is for tension)?
