Answer 2

Answer:

Explanation:

Assertion : The numerical ratio of displacement to distance is equal to one or less than one.

Reason : Displacement is a vector quantity and distance is a scalar quantity.

explanation : Displacement is the minimum seperation between two points. it doesn't depend on path. This is because displacement is a vector quantity. it has direction. it can be found by the difference of final position to initial position.

distance is the length of path covered by a particle. it depends on path of particle. this is because distance is a scalar quantity. it doesn't have direction.

[so reason is correct]

in straight line path of a particle,

distance = displacement

in non linear path of a particle,

distance > displacement

from explanation of both terms it is clear that

|displacement| ≤ |distance |

⇒|displacement|/|distance| ≤ 1 [ so assertion is correct]

here assertion and reason both are correct also reason is correct explanation of assertion.
