Spring of spring constant $1200\, Nm^{-1}$ is mounted on a smooth frictionless surface and attached to a block of mass $3\, kg$. Block is pulled $2\, cm$ to the right and released. The angular frequency of oscillation is .... $ rad/sec$

A

$5$

B

$30$

C

$10$

D

$20$

Solution

Angular frequency

$\omega=\sqrt{\frac{\mathrm{K}}{\mathrm{m}}}=\sqrt{\frac{1200}{3}}=20 \mathrm{rad} / \mathrm{sec}$
