Time period of SHM

The differential equation of motion of a particle executing SHM is \(\frac{d^2y}{dt^2} + Ky = 0\) where K is positive constant. The time period of the oscillation is given by
\(\frac{2\pi}{K}\)
\(2\pi K\)
\(\frac{2\pi}{\sqrt{K}}\)
\(2\pi\sqrt{K}\)

Solution:

Comparing with the standard equation of SHM, \(\frac{d^2y}{dt^2} + \omega^2 y = 0\), we get \(\omega = \sqrt{K}\). Therefore, the time period is \(T = \frac{2\pi}{\omega} = \frac{2\pi}{\sqrt{K}}\).
