    What is the velocity of the bob of a simple pendulum at its mean position, if it is able to rise to vertical height of \[10cm\] (Take \[g=9.8\,m/{{s}^{2}})\]                                  [BHU 2000]

    A)                 0.6 m/s

    B)                 1.4 m/s

    C)                 1.8 m/s

    D)                    2.2 m/s

    Correct Answer: B

    Solution :

                        \[v=\sqrt{2gh}=\sqrt{2\times 9.8\times 0.1}=\sqrt{1.96}=1.4\,m/s\]
