Question

a particle moves 3m north then 4m east and finally 6m south calculate the displacement​

Answer 1

Answer:

- 5m

Explanation:

In attachment red line represents displacement.

 Using Pythagoras theorem:

⇒ displacement^2 = 3^2 + 4^2

              = 9 + 16

              = 25

Displacement = ± 5 m.

 As it moves in backward direction, displacement is - 5m.
