1.The numerical ratio of displacement to distance for a moving object is:
a)always less than 1
b)always equal to 1
c)always grater than 1
d)equal to 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 and zero when there is no motion.
So, ratio of displacement to distance is always equal to or less than 1.
Correct option is d..
