    The displacement of a body at a particular second n is given by the expression \[{{S}_{nth}}=u+\frac{a}{2}(2n-1)\]. The dimensional formula of \[{{S}_{nth}}\] in this equation is   

    A)    \[[{{M}^{1}}{{L}^{0}}{{T}^{1}}]\]

    B)    \[[{{M}^{0}}{{L}^{1}}{{T}^{0}}]\]

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

    D)  \[[{{M}^{0}}{{L}^{0}}{{T}^{0}}]\]

    Correct Answer: C

    Solution :

    [c] \[[{{S}_{n}}]=[{{M}^{o}}{{L}^{1}}{{T}^{o}}]\]
