The various displacements of airplane is shown below <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/bac5c449da180b8e711d1f7eb8cf3cdb-.png" /> Net displacement travelled by airplane, d=√1002+12002=√1450000 =1204.16 m =1200 m

Q. An airplane flies $400 m$ north and $300 m$ south and then flies $1200 m$ upwards then net displacement is

1400 m

1500 m

1200 m

1100 m

The various displacements of airplane is shown below

Net displacement travelled by airplane,
$d = 10 0^{2} + 120 0^{2} = 1450000$
$= 1204.16 m = 1200 m$

Q. An airplane flies 400m north and 300m south and then flies 1200m upwards then net displacement is
