  • question_answer
    A satellite with kinetic energy \[{{E}_{k}}\] is revolving round the earth in a circular orbit. How much more kinetic energy should be given to it so that it may just escape into outer space           [KCET (Engg./Med.) 2001]

    A)             \[{{E}_{k}}\]

    B)             2\[{{E}_{k}}\]

    C)             \[\frac{1}{2}{{E}_{k}}\]      

    D)             3\[{{E}_{k}}\]

    Correct Answer: A

    Solution :

        Binding energy = ? kinetic energy And if this amount of energy \[({{E}_{k}})\] given to satellite then it will escape into outer space
