Two astronauts are floating in gravitational free space after having lost contact with their spaceship. The two will

(1) move towards each other
(2) Move away from each other
(3) Will become stationary
(4) Keep floating at the same distance between them

Solution: The correct answer is option (1).

Both astronauts are in a state of weightlessness. The gravitational attraction between them pushes them together.
