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.
