    A thin rod of mass M acts as a compound pendulum. Distance between centre of suspension and centre of mass is d. Moment of inertia about axis of suspension of\[I.\]Then distance between centre of suspension and centre of oscillation is:

    A) \[\frac{I}{Md}\]                               

    B)        \[\frac{I}{2Md}\]                             

    C)        \[\frac{I}{12Md}\]                          

    D)                        \[\frac{3I}{4Md}\]

    Correct Answer: A

    Solution :

                    On using a rod as simple pendulum, distance of centre of suspension from centre of oscillation is \[\frac{I}{Md}\].
