    There are two planets and the ratio of radius of the two planers is K but ratio of acceleration due to gravity of both planets is g. What will be the ratio of their escape velocity?

    A) \[{{(Kg)}^{1/2}}\]            

    B)        \[{{(Kg)}^{-1/2}}\]          

    C)        \[{{(Kg)}^{2}}\]                

    D)        \[{{(Kg)}^{-2}}\]

    Correct Answer: A

    Solution :

                    \[{{v}_{e}}=\sqrt{Rg}\] \[\frac{{{v}_{1}}}{{{v}_{2}}}=\sqrt{\frac{{{R}_{1}}}{{{R}_{2}}}\cdot \frac{{{g}_{1}}}{{{g}_{2}}}}\]     \[=\sqrt{Kg}\]     \[={{(Kg)}^{1/2}}\]
