Question

A balloon is filled with air, and held with its mouth downwards. When the balloon is released the air rushes out vertically downwards and the balloon moves vertically upwards. Which law of physics applies here.​

Answer 1

Answer:

If a balloon filled with compressed air and its mouth untied is released with its mouth in the downward direction, the balloon moves in the upward direction because the air present in the balloon rushes out in the downward direction. The equal and opposite reaction of downward going air pushes the balloon upwards.
