A particle of mass m is thrown upwards from the surface of the earth, with a velocity u. The mass and the radius of the earth are, respectively, M and R. G is gravitational constant and g is acceleration due to gravity on the surface of the earth. The minimum value of u so that the particle does not return back to earth, is

$$\sqrt {{{2GM} \over {{R^2}}}} $$

$$\sqrt {{{2GM} \over R}} $$

$$\sqrt {{{2gM} \over {{R^2}}}} $$

$$\sqrt {2g{R^2}} $$
