Question

A train is moving towards east and a car is along north, both with same speed. The observed direction of car to the passenger in the train is(a) east-north direction(b) west-north direction(c) south-east direction(d) None of the above

Answer 1

b. North- west direction

Answer 2

Answer:

North West Direction

Explanation:

To find out the solution for the question, we need to consider two vectors along with the directions of the train and the car. Next we will find out the apparent direction carefully observed from the train. We will take a vector on the opposite direction of the train that is in the west direction.  

Now when we will find out the resultant vector which is the diagonal of the square consist of two vectors in the direction of west and north. And thus the result will be precisely Northwest.

However, since both the objects are moving in perpendicular directions the resultant direction of their velocity vector may  be in North East direction but, the observed direction will be perpendicular to each other. Thus, the observer from the train will see the car is going to the northwest.
