Direction: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:
Assertion : If a particle is moving with constant velocity, then average velocity for any time interval is equal to instantaneous velocity.
Reason : If average velocity of a particle moving on a straight line is zero for a given time interval, then instantaneous velocity at some instant within this interval may be zero.
- a)Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
- b)Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
- c)Assertion (A) is true but reason (R) is false.
- d)Assertion (A) is false but reason (R) is true.
Correct answer is option 'B'. Can you explain this answer?

Average velocity Vav = Total displacement/Total elapsed time = Vt/t = V

= Instantaneous velocity
Hence, assertion is correct. If a particle is in a round trip on a straight line, then average velocity is zero but at the instant at which the particle reverses its direction of motion, velocity is zero.
So, reason is correct. But reason is not the correct explanation of assertion.

Answer:
Assertion: If a particle is moving with constant velocity, then the average velocity for any time interval is equal to the instantaneous velocity.
Reason: If the average velocity of a particle moving on a straight line is zero for a given time interval, then the instantaneous velocity at some instant within this interval may be zero.
Explanation:
Velocity is a vector quantity that describes the rate of change of an object's position with respect to time. It has both magnitude and direction. Average velocity is calculated by dividing the displacement of an object by the time taken to cover that displacement. Instantaneous velocity, on the other hand, is the velocity of an object at a specific instant in time.
Constant Velocity:
When a particle is moving with a constant velocity, it means that its speed and direction remain constant over time. In other words, the object covers equal distances in equal intervals of time. If the velocity is constant, the average velocity for any time interval will be equal to the instantaneous velocity.
Explanation of Assertion:
When a particle is moving with constant velocity, it means that the average velocity for any time interval will be equal to the instantaneous velocity. This is because the object covers equal distances in equal intervals of time, indicating a constant velocity throughout the motion. Therefore, the assertion is true.
Explanation of Reason:
If the average velocity of a particle moving on a straight line is zero for a given time interval, it means that the object covered equal distances in equal intervals of time in opposite directions. In this case, the instantaneous velocity at some instant within this interval may be zero. This is because the object may have changed its direction during the given time interval, resulting in a momentary zero velocity at some instant. Therefore, the reason is also true.
Conclusion:
Both the assertion and reason are true, but the reason is not the correct explanation of the assertion. The reason provides additional information about the possibility of the instantaneous velocity being zero within a given time interval when the average velocity is zero. However, it does not directly explain why the average velocity for any time interval is equal to the instantaneous velocity when the particle is moving with constant velocity. Hence, the correct answer is option 'B'.
