    The dimensional formula for relative density is

    A)  \[[M{{L}^{-3}}]\] 

    B)  \[[{{M}^{o}}{{L}^{-3}}]\]

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

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

    Correct Answer: D

    Solution :

    [d] \[Relative\text{ }density\text{ }=\frac{Density\,of\,Subs\tan ce}{Density\,of\,water}\] Hence no dimension.
