Question
A particle of mass m is 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 of the surface of the earth. The minimum value of u so that the particle does not return back to earth, is
Options
A.
B.
C.
D.
