    If a spring of force constant\[k\]is divided into n equal parts and one such part is attached to a mass m then the period is given by

    A)  \[T=2\pi \sqrt{m/k}\]

    B)  \[T=2\pi \sqrt{nm/k}\]

    C)  \[T=2\pi n\sqrt{m/k}\]

    D)  \[T=2\pi \sqrt{m/nk}\]

    Correct Answer: D

    Solution :

    : If a spring of constant k is divided into n equal parts, the spring constant for each part becomes\[(nk)\] \[\therefore \] \[T=2\pi \sqrt{\frac{m}{nk}}\]
