Question

I started walking down a road facing the sun. After walking for some time, I turned to left, then I turned to right once again. In which direction was I going then.
A. East
B. North-west
C. North-east
D. South

Answer 1

Hint: In this question we have been asked to track the direction of a man under given conditions. It is given that he is initially facing the sun and walks for some time and turns left. After walking a few distances, he takes a right. We are asked the direction to which the man is facing at the end. We will solve this question by tracking the path and using vectors for displacement.

Complete answer:
We know that the position of sun at the time of daybreak is in the east as shown in the figure below.

              

It is given that the man started walking at daybreak facing the sun. It said that he then takes a left turn and continues as shown in the figure by path 2. He then takes a turn to left which is shown in the figure by path 3.
Now, assuming that the man took a sharp 90 degrees turn. The position of man is as shown in path 3 in the above figure.
From the figure, we can say that the man is now moving in the east direction.

So, the correct answer is “Option A”.

Note:
Displacement of a body implies that an object has moved from some initial position. It is basically a change in position. The displacement vector is independent of the path taken by the object. In this question were asked the direction in which the man was now moving. Therefore, we did not use the concept of displacement.
