A vehicle moves from point P to Q to R to S in a circular path as shown in the below fig Find out the magnitude of the displacement of the vehicle in km.

To find the magnitude of the displacement of the vehicle, we need to consider the distance between the starting point (P) and the final point (S) in the circular path.

1. First, identify the distance between P and Q. This can be measured using a ruler or by estimating the distance on the figure. Let's say this distance is 2 km.

2. Next, determine the distance between Q and R. Again, measure or estimate this distance. Let's say it is 3 km.

3. Finally, calculate the distance between R and S. Measure or estimate this distance as well. Let's say it is 4 km.

4. To find the magnitude of the displacement, add up the distances between each consecutive point: 2 km + 3 km + 4 km = 9 km.

Therefore, the magnitude of the displacement of the vehicle in the circular path is 9 km.
