A uniform rod of mass M = 2 kg and length L is suspended by two smooth hinges 1 and 2 as shown in Fig. A force F = 4 N is applied downward at a distance L//4 from hinge 2 . Due to the application of force F , hinge 2 breaks. At this instant, applied force F is also removed. The rod starts to rotate downward about hinge 1 . ( g = 10 m//s^(2) ) The acceleration of the end point of the rod of small mass dm at the end point of the rod, when the rod becomes vertical is
