@chetan,sorry for not describing it right.Basically its best explained with the help of figure…Its from mechanics section of gate ’05(mech).Its like an elevator and counterbalance system.The two weights are freely suspended over a pulley by means of an inextensible string.One mass is moving up with velocity ‘v’ so naturally the other is going down with ‘v’.Sorry for replying late.
