Question
Two persons of mass m1 and m2 are standing at the two ends A and B respectively, of a trolley of mass M as shown When both the persons jump simultaneously with same speed then
- the centre of mass of the system remains stationary
- the trolley remains stationary
- the trolley moves toward the end where the person with heavier mass is standing
- None of these
The correct answer is: the centre of mass of the system remains stationary
