Achild walks 5 meters north, then 4 meters east and finally 2 meters south. what is the magnitude of resultant displacement of the child after the entire walk?
a. 1m b. 3m c. 5m d. 11m

The magnitude of resultant displacement of the child after the entire walk is 5 m.

(c) is correct option.

Explanation:

Given that,

A child walks 5 meters north,then 4 meters east and finally 2 meters south.

According to figure,

Here, EB =CD

So, AE = AB-EB

AE = 5-2 = 3 meters

We need to calculate the magnitude of resultant displacement of the child after the entire walk

Using Pythagorean theorem

Put the value into the formula

Hence, The magnitude of resultant displacement of the child after the entire walk is 5 m.
