An aeroplane 400 m north and 300 m south and then flies 1200 m upwards then net displacement is?
Correct answer: B. 1300 m
- A. 1200 m
- B. 1300 m
- C. 1400 m
- D. 1500 m
Explanation
An aeroplane flies 400 m north and 300 m south so the net displacement is 100 m towards north. Then it flies 1200 m upward so r = 1200+100 =1300=1300m The option should be 1300 m, and the net displacement is in upward direction only.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
