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

  1. the centre of mass of the system remains stationary    
  2. the trolley remains stationary    
  3. the trolley moves toward the end where the person with heavier mass is standing    
  4. None of these    

The correct answer is: the centre of mass of the system remains stationary
