    When a mass undergoes SHM there is always a constant ratio between its displacement and:

    A)  period              

    B)  acceleration

    C)  mass              

    D)  velocity

    Correct Answer: B

    Solution :

    As we know that, \[\alpha ={{\omega }^{2}}x\] (in magnitude)             \[\Rightarrow \]   \[\alpha ={{\left( \frac{2\pi }{T} \right)}^{2}}x\]             \[\Rightarrow \]   \[T=2\pi \,\sqrt{\frac{x}{a}}\]                         \[\varepsilon =\sqrt{\frac{displacement}{acceleration}}\] and T in SUM is constant Therefore, ratio (displacement/acceleration) is constant.
