A boy of mass 40 kg stands in a frame of mass 360 kg. He pulls on a light rope which passes over a pulley. The other end of the rope is firmly attached to the frame. What force should be exerted by the boy on the rope for the system to be in equilibrium ? ( g= acceleration due to gravity)
- 40 g
- 400 g
- 200 g
- 100 g
The correct answer is: 200 g
