Q113 / 200 · NEET 2004 · Physics

Which one of the following statements is true for the speed $v$ and the acceleration $a$ of particle executing simple harmonic motion?

  • A
    When $v$ is maximum, $a$ is maximum
  • B
    Value of $a$ is zero, whatever may be value of $v$
  • C
    When $v$ is zero, $a$ is zero
  • Correct answer
    D
    When $v$ is maximum $a$ is zero

Solution

In SHM $\text {Velocity }=A \omega \sin \left(\omega t+\frac{\pi}{2}\right)$ Acceleration $= A \omega^2 \sin (\omega t+\pi)$ This shows that $V$ is max then $a=0$

Hence, the correct answer is option: 'D'.
