QUËSTIONS:-

An object travels 4 km from A to B towards north and then 3 km from B to C towards west. Find its displacement.

ANSWER:- displacement

[tex] {x}^{2} = {3 }^{2} + {4}^{2} \\ {x}^{2} = 9 + 16 \\ {x}^{2} = 25 \\ x = \sqrt{25} \\ x = 5[/tex]

displacement = 5 km

Explanation:

We nee to use triangle law

As displacement is the shortest path travelled, we take A-C

so, D=√4^2+3^2

D=5km
