    A simple pendulum of length\[l\]has a maximum angular displacement Q. The maximum kinetic energy of the bob is

    A)  \[mgf(1-cos\theta )\]                   

    B)  \[0.5\text{ }mgl\]

    C)  \[mgl\]                               

    D)  \[2\,mgl\]

    Correct Answer: A

    Solution :

                    \[h=l-l\cos \theta =l(1-\cos \theta )\]\[mgh=mgl\text{ }(1-cos\theta )\]
