A uniform rod AB of mass m = 2 kg and length l = 1.0 m is placed on a sharp support P such that a = 0.4 m and b = 0.6 m. A. spring of force constant k= 600 N//m is attached to end B as shown in Fig. To keep the rod horizontal, its end A is tied with a thread such that the spring is B elongated by 1 CM. Calculate reaction of support P when the thread is burnt. |
