In the absence of gravitational force of attraction, propulsion on the rocket is:
A. stable at the rate of exhaust gas is constant
B. stable for short range rockets
C. not stable
D. stable
Answer: Option D
Solution (By Examveda Team)
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.
