    What is the effect on the time period of a simple pendulum, if the mass of the bob is doubled?

    A)  Halved

    B)  Doubled

    C)  Becomes eight times

    D)  Becomes zero

    E)  No effect

    Correct Answer: E

    Solution :

                    The time period of a simple pendulum is\[T=2\pi \sqrt{\frac{l}{g}}\]where \[l\] is length of suspension of pendulum, g is acceleration due to gravity. From the above expression, it is clear that time period of a simple pendulum is not dependent on the mass of bob, hence no effect.
