प्रश्न
'When a hanging carpet is beaten with a stick, the dust particles start coming out of it'. This phenomenon can be best explained by making use of :
विकल्प
Newton's third law of motion
Newton's law of gravitation
Newton's first law of motion
Newton's second law of motion

उत्तर
Newton’s first law of motion
This is because beating the carpet with a stick makes the carpet move to-and-fro quickly, but the dust particles tend to remain at rest due to their inertia and get separated from the carpet.
