In the arrangement shown in figure , the mass of ball 1 is (n=1.8) times larger than that of rod 2 . Thelength of rod is 1=1m . The ball is set on the same level as the lower end of the rod and then released , find the time taken by the ball to reache at the level of the upper end of the rod. The masses of pulleys , threads and the friction may be neglected .
