Question

Pick the correct option based on following statements.
(A) Average speed of a particle can never be less than the magnitude of average velocity.
(B) We may come across $\left|\frac{d\overrightarrow{v}}{dt}\right|\ne 0$ but $\frac{d}{dt}\left|\overrightarrow{v}\right|=0$.
(C) The average velocity of a particle is zero in a time interval but instantaneous velocity is never zero in that interval.

• A. Only A and B are correct
• B. Only B and C are correct
• C. Only A and C are correct
• D. A, B and C are correct

Answer 1

The correct option is D A, B and C are correct

All are correct statements.
Example: Uniform circular motion, for options (B) and (C).
Since, displacement can be less than distance, average speed can not be less than magnitude of average velocity.
