Question

Two pulley arrangements of figure given are identical. The
mass of the rope is negligible. In fig (a), the mass m is lifted
by attaching a mass 2m to the other end of the rope. In fig
(b), m is lifted up by pulling the other end of the rope with a
constant downward force F = 2mg. The acceleration of m in
the two cases are respectively
(a) 3g, g (b) g /3, g
(c) g /3, 2g (d) g, g /3

Explanation:

(b), m is lifted up by pulling the other end of the rope with a

constant downward force F = 2mg. The acceleration of m in

the two cases are respectively

(a) 3g, g (b) g /3, g

(c) g /3, 2g (d) g, g /3
