Answer 1

Answer: (A), (D)

The correct options are
A A displacement of 10 km towards the North.
D Aeroplane is travelling from Kolkata to Mumbai with a speed of 500 km/hr.


Vector quantity is a quantity which has magnitude as well as direction. 'A displacement of 10 km towards North' has both magnitude as well as direction. Similarly 'Aeroplane is travelling from Kolkata to Mumbai with a speed of 500 km/hr' has both the magnitude as well as direction. Hence a vector quantity.
