When we strike a hanging carpet with a stick, dust particles come out of it. This phenomenon can be explained by the concept of inertia of motion.

Inertia of motion is the tendency of an object to resist a change in its state of motion. According to Newton's first law of motion, an object at rest will remain at rest, and an object in motion will continue to move with a constant velocity unless acted upon by an external force.

When we strike the carpet with a stick, the force applied by the stick causes the carpet to move forward and backward. This change in motion is resisted by the dust particles present in the carpet.

The dust particles, being at rest initially, tend to remain at rest due to their inertia. As the carpet moves forward, the dust particles try to stay in their initial position. However, the force exerted by the carpet on the dust particles causes them to overcome their inertia and move forward.

Therefore, the correct options are (b) and (c) - the dust particles remain at rest initially (due to their inertia) and then start moving forward (due to the force exerted by the carpet).

To summarize:
- When the carpet is struck with a stick, it starts moving forward and backward.
- The dust particles present in the carpet, being at rest initially, tend to remain at rest due to their inertia.
- However, the force exerted by the carpet on the dust particles causes them to overcome their inertia and move forward.
- This is why dust particles come out of a hanging carpet when we strike it with a stick.

The dust particle come out because the body is in rest so it is try to be in rest
