उत्तर
- The 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 into 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.
