The natural angular frequency of a particle of mass 'm' attached to an ideal spring of force constant 'K' is

AnswerClick to flip back
A
$\sqrt{\frac{K}{m}}$
💡 Explanation:
Suppose you displace the particle by a distance $'x'$
The spring now exerts a force,
This provides nccenary force for $SHM$
$\Rightarrow \ F=mwe^2x=k2$ ($w:$ natural angular frequency )
$\Rightarrow \ w=\sqrt {K/m}$
