Question
Two bodies of masses 15gm and 25gm are connected by means of a string of length 40 cm and mass 10gm. The string is made to pass over a smooth massless pulley. Initially the two bodies are kept at the same level and released. By the time the heavier mass descends by 10 cm, the acceleration of the system,
- Remains constant
- Decreases
- Increases by a factor 1.5
- Increases by a factor 3
The correct answer is: Increases by a factor 1.5

A light straight fixed at one end to a wooden clamp on a ground passes over a fixed pulley and hangs at the other side. It makes an angle 30° with the ground. A boy weighing 60 kg climbs up the rope. The wooden clamp can tolerate up to vertical force 360 N. Find the, maximum acceleration in the upward direction with which the boy can climb safely. The friction of pulley and wooden clamp may be ignored
