NEET Physics Speed & Velocity Assertion Reason Question
Assertion (A): Instantaneous velocity can be obtained as the limiting value of average velocity as the time interval approaches zero.
Reason (R): The instantaneous velocity is always equal to the average velocity over any time interval.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
According to the NCERT context, instantaneous velocity is defined as the limiting value of average velocity as the time interval approaches zero. However, instantaneous velocity is not always equal to the average velocity over any interval.
