Newton's Law of Gravitation: Practice Problem & Solution

Two astronauts are floating in gravitational free space after having lost contact with their spaceship. The two will: (2017-Delhi)
Move towards each other
Move away from each other
Will become stationary
Keep floating at the same distance between them

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Newton's Law of Gravitation. Understanding the underlying formula is key to arriving at the correct answer below:

Due to universal gravitational attraction between the two astronauts, they will experience a mutual attractive force and move towards each other in space.
