    The escape velocity for a body projected vertically upwards from the surface of earth is 11 km/s. If the body is projected at an angle of \[45{}^\circ \] with the vertical, the escape velocity will be

    A) \[22\,km/s\]       

    B)        \[11\,km/s\]

    C) \[\frac{11}{\sqrt{2}}\,km/s\]       

    D)        \[11\sqrt{2}\,km/s\]

    Correct Answer: B

    Solution :

    [b] Since escape velocity \[\left( {{v}_{e}}=\sqrt{2g}{{R}_{e}} \right)\] is independent of angle of projection, so it will not change.
