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

1. move towards each other.
2. move away from each other.
3. become stationary.
4. keep floating at the same distance between them.

Correct answer: move towards each other.

Solution

In the absence of external forces, the gravitational force between the two astronauts will cause them to attract each other and move closer.
