Question

The numerical ratio of displacement to distance for a moving object is

• A. always less than 1
• B. always equal to 1
• C. always more than 1
• D. equal or less than 1

Answer 1

The correct option is D equal or less than 1

We know, magnitude of displacement is the straight line distance between the initial and final point of the path of a moving body.
Displacement can be positive, negative or zero.
While distance travelled is always positive or zero when there is no motion.
So the ratio of displacement to distance is always equal to or less than 1.
