    If the acceleration due to gravity is\[10\text{ }m{{s}^{-2}}\]and the units of length and time are changed to kilometre and hour respectively, the numerical value of the acceleration due to gravity is:

    A)  360000                

    B)         72000  

    C)         36000                  

    D)         129600

    E)  73000

    Correct Answer: D

    Solution :

    \[{{n}^{2}}=10\left[ \frac{m}{km} \right]{{\left[ \frac{s}{h} \right]}^{-2}}\] \[=10\left[ \frac{m}{1000m} \right]{{\left[ \frac{s}{3600s} \right]}^{-2}}\] \[=129600\]
