    A body is projected vertically upwards from the surface of earth with a velocity equal to one third of escape velocity. The maximum height attained by the body will be: (Take radius of earth =6400 km= 6400\text{ }km and g=10 ms−2g = 10{\text{ }ms}^{- 2} )

    A body of mass mm is projected with velocity λve\lambda v_{e} in vertically upward direction from the surface of the earth into space. It is given that vev_{e} is escape velocity and λ<1\lambda < 1. If air resistance is considered to the negligible, then the maximum height from the centre of earth, to which the body can go, will be ( RR : radius of earth)
