    The percentage change in the time period of a seconds pendulum when its amplitude is reduced by 50% is:

    A)  75%                                      

    B)  25%

    C)  0%                                        

    D)  50%

    Correct Answer: C

    Solution :

                     The time period of pendulum is\[T=2\pi \sqrt{\frac{l}{g}}\] It is quite clear from relation of time period, that time period of pendulum does not depend upon the amplitude hence time period of seconds pendulum will remain same i.e., change is 0%
