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

Answer:

d) equal or less than 1

Explanation:

Displacement is nothing but shortest distance. Hence it can never be more than distance.

But in some cases, if the tranversed path is along the displacement path then displacement and distance becomes equal.

So option (d) is right.

Answer 2

Answer:

equal to or less than 1

Explanation:

Distance is scalar quantity, it is never negative.

Therefore distance can be equal or greater than displacement. That implies ratio of of displacement to distance is always equal to or less than 1
