Question
Assertion : In simple harmonic motion, the velocity is maximum when acceleration is minimum
Reason : Displacement and velocity of S.H.M. differ is phase by
✓

Answer

(b) $x=a \sin \omega t$ and $v=\frac{d x}{d t}=a \omega \cos \omega t$It is clear phase difference between ' $x$ ' and ' $a$ ' is $\pi / 2$.
