Question

A man of mass m stands on a create of mass M. He pulls on a light rope passing over a smooth light pulley. The other end of the rope is attached to the crate. For the system to be in equilibrium, the force exerted by the men on the rope will be

Options:

A . (M+m)g

B . 12(M+m)g

C . Mg

D . mg

Answer: Option B
:
B
From the free body diagram of man and crate system: For vertical equilibrium
2T = (M + m)g

∴ T = \frac{(M + m)}{2} g
