An isolated particle of mass rn is moving in a horizontal plane (x-y) along the X-axis. At a certain height above the ground, it suddenly explodes into two fragments of masses . An instant later, the smaller fragment is at Y = +15 cm. The larger fragment at this instant is at:
detailed solution
Correct option is A
Initially coordinates of centre of mass is origin. Explosion is an internal force. That is after explosion the coordinate of centre of mass of the particles should be origin.m4×(15) = 34m(Y) = 0 ⇒ Y = -5 cmSimilar Questions
