Question

Assertion (A): A body may have velocity and displacement in the opposite directions.

Reason (R): Velocity is the distance traveled by the body in a unit of time.

• A. A and R are correct and R is the correct explanation for A.
• B. A and R are correct but R is not the correct explanation for A.
• C. A is correct but R is incorrect.
• D. Both A and R are incorrect

Answer 1

The correct option is D

Both A and R are incorrect

Explanation for the assertion statement:

1. The displacement and velocity are always in the same direction
2. The velocity describes the change in displacement with time.
3. $velocity=\frac{displacement}{time}$
4. As the velocity and displacement are the vector quantity, thus, the direction of velocity is the same as of direction of displacement.
5. Thus, the assertion is incorrect.

Explanation for the reason statement:

1. Velocity is the displacement of the body in unit time.
2. $velocity=\frac{displacement}{time}$

Therefore, both assertion and reason are incorrect.

Hence, option D is correct.
