Question

17. When a carpet is beaten with a stick it releases dust. Why?

Answer 1

When a carpet is beaten with a stick, it comes into motion. But the dust particles continue to be at rest due to inertia and get detached from the carpet.

Hope it helps you :)

Answer 2

Hey Ansh Your answer goes like this -
As on beating the carpet with the stick, the carpet moves ahead & by inertia of rest dust particles remain in rest but when they came in air they are no more in contact with the carpet & due to gravity of earth they fall down.
