Question

'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 :

(a) Newton's third law of motion
(b) Newton's law of gravitation
(c) Newton's first law of motion
(d) Newton's second law of motion

Answer 1

(c) 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.
