    The dimensional formula of physical quantity is \[{{M}^{a}}{{L}^{b}}{{T}^{c}}\] Then that physical quantity is

    A)  surface tension if \[a=1,\,b=1,\,c=-2\]

    B)  Force if \[a=1,\,b=1,\,c=2\]

    C)  Angular frequency if \[a=0,\,b=0,\,c=-1\]

    D)  Spring constant if \[a=1,\,b=-1,\,c=-2\]

    Correct Answer: C

    Solution :

    : Angular frequency \[=2\pi \times \] Frequency \[=[{{T}^{-1}}]=[{{M}^{0}}{{L}^{0}}{{T}^{-1}}]\] \[\therefore \] \[a=0,\,b=0,\,c=1\]
