Question
Which of the two persons shown in figure is more likely to fall down? Which external force is responsible for his falling down?
✓
Answer
The person sitting on right side of the figure is likely to fall Because of moment of inertia of the body of person his upper body is still in rest but lower body that is in contact with seat due to friction may move forward (right) as center of mass may be at the center of body the man may fall towards left.
