The pulley arrangements shown in figure are identical, the mass of the rope being negligible. In case I the mass m is lifted by attaching a mass `2m` to the other end of rope with a constant downward force `F =2mg`, where g is acceleration due to gravity The acceleration of mass m in case I is
.

The pulley arrangements of Figs. (a) and (b) are identical. The mass of the rope is negligible. In (a) the mass m is lifted up by attaching a mass 2m to the other end of the rope. In (b), m is lifted up by pulling the other end of the rope with a constant downward force F=2mg . The acceleration of m is the same in both cases

In (b) m is lifted up by pulling the other end of the rope with a constant downward force F = 2 mg. Which of the following is correct?

The pulley arrangement in Fig are identical .The mass of the rope is negligble in figure the mass m is lifted up by atteched a mass 2m to the other end of the rope . In (b), m is lifed up by pulley the other end of the rope with a constant in both cases
