    The moment of inertia of a solid sphere, about an axis parallel to its diameter and at a distance of x from it, is 'I(x)'. Which one of the graphs represents the variation of l(x) with x correctly?

    A)

    B)

    C)    

    D)

    Correct Answer: D

    Solution :

    \[I={{I}_{CM}}+M{{x}^{2}}\] \[{{I}_{CM}}=\frac{2}{5}M{{R}^{2}}\] \[\Rightarrow \] \[I=\frac{2}{5}M{{R}^{2}}+M{{x}^{2}}\]
