$\mathrm{V}_{\max }=\beta \Rightarrow \omega \mathrm{A}=\beta$ $...(2)$
Dividing
$\omega=\frac{\alpha}{\beta} \Rightarrow n=\frac{\alpha}{2 \pi \beta}$
$(A)$ Restoring force is directly proportional to the displacement.
$(B)$ The acceleration and displacement are opposite in direction.
$(C)$ The velocity is maximum at mean position.
$(D)$ The acceleration is minimum at extreme points.
