Q: 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
Correct Answer: Option D - Rockets are based on Newton third Law of motion (action-reaction). Solid or liquid fuel is ignited in a chamber within the rocket in the presence of oxygen, which produces gas at high pressure. In the absence of gravitational force the Propulsion on the rocket is stable.
D. Rockets are based on Newton third Law of motion (action-reaction). Solid or liquid fuel is ignited in a chamber within the rocket in the presence of oxygen, which produces gas at high pressure. In the absence of gravitational force the Propulsion on the rocket is stable.
