    The dimensional formula for Boltzmann's constant is?                               [MP PET 2002; Pb. PET 2001]

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

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

    C)             \[[M{{L}^{0}}{{T}^{-2}}{{\theta }^{-1}}]\]

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

    Correct Answer: A

    Solution :

                    \[k=\left[ \frac{R}{N} \right]=[M{{L}^{2}}{{T}^{-2}}{{\theta }^{-1}}]\]
