    If \[{{V}_{e}}\] is escape velocity and \[{{V}_{o}}\] is orbital velocity of a satellite for orbit close to the Earth's surface, then these are related by

    A) \[{{v}_{o}}=\sqrt{2}{{v}^{e}}\]  

    B) \[{{v}_{o}}={{v}^{e}}\]  

    C) \[{{v}_{e}}=\sqrt{2{{v}^{e}}}\]  

    D) \[{{v}_{e}}=\sqrt{2}{{v}_{o}}\]

    Correct Answer: C

    Solution :

    Orbital velocity of satellite \[{{v}_{0}}=\sqrt{\frac{GM}{R}}\]                                             ?(i) and escape velocity of satellite                 \[{{v}_{e}}=\sqrt{\frac{2GM}{R}}\]                                          ..(ii) Hence,     \[{{v}_{e}}=\sqrt{2}{{v}_{0}}\]
