    The dimensions of shear modulus are?                                                                                    [MP PMT 2004]

    A)             \[ML{{T}^{-1}}\]

    B)               \[M{{L}^{2}}{{T}^{-2}}\]

    C)             \[M{{L}^{-1}}{{T}^{-2}}\]

    D)               \[ML{{T}^{-2}}\]

    Correct Answer: C

    Solution :

                    Shear modulus = \[\frac{\text{Shearing stress}}{\text{Shearing strain }}\]\[=\frac{F}{A\theta }=[M{{L}^{-1}}{{T}^{-2}}]\]
