The numerical ratio of displacement and distance for a moving object is         (NCERT Exemplar)

A) always less than 1 

B) always equal to 1

C) always more than 1

D) equal to or less than 1

Correct Answer: D

Solution :

[d] Displacement of an object can be less than or equal to the distance covered by the object because the magnitude of displacement is no equal to distance. However, it can be so I the motion is along a straight line without any change in direction.

So, the ratio of displacement to distance is always equal to or less than 1.
