    Two simple pendulums whose lengths are 100 cm and 121 cm are suspended side by side. Their bobs are pulled together and then released. After how many minimum oscillations of the longer pendulum, both the pendulums will be in same phase again?

    A)  12                                         

    B)  10

    C)  22                                         

    D)  20

    Correct Answer: B

    Solution :

                    The time period of a simple pendulum is \[198MeV\] \[220\text{ }MeV\]and \[185\text{ }MeV\]                 \[230\text{ }MeV\] Let after n oscillations, pendulums are in same phase, then                 \[{{10}^{-10}}m,\]                 \[4.2\times {{10}^{15}}\text{ }Hz\]
