Question

Jet propulsion works on the principle of________

(a) Newton’s first law

(b) Newton’s second law

(c) Newton’s third law

(d) Thermodynamic properties

I got this question in an interview.

I'm obligated to ask this question of Force Exerted by a Jet on a Stationary Curved Plate topic in chapter Impact of Jets and Jet Propulsion of Fluid Mechanics

Answer 1

Correct choice is (c) Newton’s third law

For explanation I would say: Jet propulsion works on the principle of Newton’s third law. Newton’s third law states that for every action, there is an equal and opposite reaction. Thus, the correct option is Newton’s third law.
