The velocity of a particle executing a simple harmonic motion is \(13 \mathrm{~ms}^{-1}\), when its distance from the equilibrium position (Q) is \(3 \mathrm{~m}\) and its velocity is \(12 \mathrm{~ms}^{-1}\), when it is \(5 \mathrm{~m}\) away from \(\mathrm{Q}\). The frequency of the simple harmonic motion is
(A) \(\frac{5 \pi}{8}\)
(B) \(\frac{5}{8 \pi}\)
(C) \(\frac{8 \pi}{5}\)
(D) \(\frac{8}{5 \pi}\)
Ans(B)
