A massless rope is passed over a frictionless pulley. A monkey holds on to one end of the rope and a mirror having the same weight as the monkey, is attached to the other end of the rope at the monkey's level. Can the monkey get away from his image seen in the mirror by climbing down the rope.

A pair of parallel horizontal conducting rails of negligible resistance shorted at one end is fixed on a table. The distance between the rails is L. A conducting massless rod of resistance R can slide on the rails frictionlessly. The rod is tied to a massless string which passes over a pulley fixed to the edge of the table, A mass m, tied to the other end of the string hanges vertically. A constant magnetic field B exists perpendicular to the table. If the system is released from rest, calculate. the terminal velocity achieved by the rod.

Two persons having the same mass are standing on ice-skates some distance apart on a frictionless surface.a rope is fastened around the body of a person,the other end of which si in the hand of the second person.What would happen if the second person pulls the rope?

Answer the following :- In Fig. 6.13(i) the man walks 2 m carrying a mass of 15 kg on his hands. In Fig. 6.13(ii), he walks the same distance pulling the rope behind him. The rope goes over a pulley, and a mass of 15 kg hangs at its other end. In which case is the work done greater ?
