Question
The numerical ratio of displacement to distance for a moving object is :
Options
always less than 1
equal to 1 or more than 1
always more than 1
equal to 1 or less than 1
Solution
equal to 1 or less than 1
i.e., Equal to 1 or less than 1.
Displacement is always smaller than or equal to displacement.
