NEETPhysicsGravitationMCQ+4 / −1
Two astronauts are floating in gravitational free space after having lost contact with their spaceship. The two will
  1. A
    move towards each other.
  2. B
    move away from each other.
  3. C
    will become stationary.
  4. D
    keep floating at the same distance between them.

Correct answer: A

Since two astronauts are floating in gravitational free space. The only force acting on the two astronauts is the gravitational pull of their masses, F=Gm1m2r2F = {{G{m_1}{m_2}} \over {{r^2}}}F=r2Gm1​m2​​

which is attractive in nature.
Hence they move towards each other.
