    A body is projected vertically upwards from the surface of a planet of radius r with a velocity equal to 1/3rd the escape velocity for that planet. The maximum height attained by the body is:

    A)  R/2        

    B)                         R/3                       

    C)  R/S                       

    D)         R/8

    E)  R/9

    Correct Answer: E

    Solution :

    \[{{u}^{2}}=2gh\] \[\Rightarrow \]               \[{{\left( \frac{1}{3}\sqrt{2gR} \right)}^{2}}=2gh\] \[\Rightarrow \]               \[h=\frac{R}{9}\]
