Discuss
Answer & Solution
Answer: Option D
Solution:
In the absence of gravitational force of attraction, propulsion on the rocket is stable.

This is because: according to Newton's third law of motion, every action has an equal and opposite reaction.

As the rocket expels exhaust gases: in one direction, an equal and opposite force propels the rocket in the opposite direction.

Therefore, the propulsion of a rocket is stable even in the absence of gravitational attraction.
