An example of variable mass system is _____(a) A car moving(b) A rocket taking off(c) A bicycle moving(d) A man walkingI had been asked this question in examination.My doubt is from Newton’s Second Law of Motion topic in division Laws of Motion of Physics – Class 11

Answer»

Correct choice is (b) A rocket taking off

To ELABORATE: In case of a rocket taking off, the mass of the fuel is LARGE and cannot be neglected. As the rocket starts MOVING, a large amount of fuel is getting burnt out from the nozzle, hence the TOTAL mass decreases. Hence it is a variable mass system.
