Question

A student walks 3 m north and 4 m south. The magnitude of the resultant displacement for the student is *

Answer 1

Resultant displacement = 5 m

Step-by-step explanation:

A student walks 3 m north and 4 m south.

We need to find the magnitude of the resultant displacement for the student.

He walks in the North and then in South direction. The magnitude of resultant displacement is given by :

`D=√(3^2+4^2) \\\\D=√(9+16) \\\\D=5\ m`

So, the magnitude of the resultant displacement for the student is 5 m.
