8. FORCE AND LAWS OF MOTION

medium

When a carpet is beaten with a stick, dust comes out of it. Explain.

Option A

Option B

Option C

Option D

Solution

Inertia of an object tends to resist any change in its state of rest or state of motion. When a carpet is beaten with a stick, then the carpet comes to motion. But, the dust particles try to resist their state of rest. According to Newton's first law of motion, the dust particles stay in a state of rest, while the carpet moves. Hence, the dust particles come out of the carpet.
