    A body travels uniformly a distance of \[(13.8\,\pm \,0.2)m\]in a time\[(4.0\,\pm \,0.3)s.\]The velocity of the body within error limits is

    A) \[(3.45\pm 0.2)m{{s}^{-1}}\]          

    B) \[(3.45\pm 0.3)m{{s}^{-1}}\]

    C) \[(3.45\pm 0.4)m{{s}^{-1}}\]          

    D) \[(3.45\pm 0.5)m{{s}^{-1}}\]

    Correct Answer: B

    Solution :

    Here,\[S=(13.8\pm 0.2)m\]and \[t=4.0\pm 0.3)\]sec Expressing it in percentage error, we have. \[S=13.8\pm \frac{0.2}{13.8}\times 100%=13.8\pm 1.4%\]and \[t=4.0\pm \frac{0.3}{4}\times 100%=4\pm 7.5%\] Hence, the correction option is [b].
