A plank of mass M and length L is hinged at its mid point from a fixed support in vertical plane as shown Plank is free to rotate in vertical plane about the hinge Two persons of equal mass running on the plank with same speed v relative to the plank so that angular velocity of the plank remains constant Assuming they run till running is possible then v is A a constant B independent of the separation between the persons C independent of the distance of the persons from the hinge D independent of their mass Hin
