    The graphs in figure show how the displacement x, velocity v and the acceleration a of a body vary with time t when it is oscillating with simple harmonic motion. What is the value of T?

    A) \[\frac{\pi }{9}s\]                      

    B)        \[\frac{2\pi }{9}s\]

    C) \[\frac{\pi }{3}s\]                      

    D)        \[\frac{2\pi }{3}s\]

    Correct Answer: D

    Solution :

    [d] \[A=2\] \[{{v}_{\max }}=6'\]             \[\left\{ \begin{align}   & {{v}_{\max }}=A\omega  \\  & \Rightarrow \,\,\omega =3 \\  & \And \,\,T=\frac{2\pi }{\omega } \\ \end{align} \right.\]
