    If the steel bob of a simple pendulum is replaced by a wooden bob, then its time period will

    A)  increase             

    B)         decrease

    C)  remains the same

    D)  first increases and then decreases

    Correct Answer: C

    Solution :

    Time period of a simple pendulum,                 \[T=2\pi \sqrt{\frac{l}{g}}\] where, \[l=\]length of the thread, \[g=\]acceleration due to gravity. Therefore, time period of a simple pendulum does not depend on the mass of the bob. Hence, time period of simple pendulum having a wooden bob will remain the same.
