Answer 1

Question:

Assertion: Ratio of displacement to distance is equal to either or less than one.

Reasoning: Distance is a scalar quantity whereas displacement is the vector quantity.

Answer:

• Option (a) is correct. Both A and R are true but R is not the correct explanation of A.

Why option (a) is correct!?

✴️ This is well said that ratio of displacement to distance is equal to either or less than one.

• Also this is correctly said that distance is a scalar quantity whereas displacement is the vector quantity.

But it is not a correct reason that ratio of displacement to distance is equal to either or less than one because displacement is already said to the shortest distance between initial or final position.

• Displacement ≤ Distance
