    In \[S=a+bt+c{{t}^{2}}\]. \[S\] is measured in metres and \[t\] in seconds. The unit of \[c\] is [MP PMT 1993]

    A) None

    B) \[m\]

    C) \[m{{s}^{-1}}\]

    D) \[m{{s}^{-2}}\]

    Correct Answer: D

    Solution :

    \[c{{t}^{2}}\] must have dimensions of \[L\] \[\Rightarrow \] \[c\] must have dimensions of \[L/{{T}^{2}}\] i.e. \[L{{T}^{-2}}\].
