An aeroplane flies 400 m north and 300m south and then flies 1200 m upwards then net displacement is

A

1200 m

B

1300 m

C

1400 m

D

1500 m

Text Solution

Verified by Experts

The correct Answer is:
A

Position `vecr = (400-300) hatj + 1200 hatk`
`r = sqrt((100)^2 + (1200)^2) = 1204 ~~ 1200m`
