A body is projected vertically upwards from the surface of the Earth so as to reach a height equal to the radius of the Earth. Neglecting resistance due to it, calculate the initial speed which should be imparted to the body. Mass of Earth `= 5.98 xx 10^(24) kg`, Radius of Earth `= 6400 km`, `G = 6.67 xx 10^(-11) Nm^(2) kg^(-2)`.
