Detailed Solution

A boy takes the carpet from his house and dusts it by hanging it on a wall. He uses a stick to dust the carpet and finds that the dust falls out. This happens as a result of the inertia of rest.
The inertia of rest is the tendency of a body to remain in the state of rest unless it is acted upon by an external unbalanced force. Here the dust particles were already in a state of rest. Only when there is an external force, such as the man striking the carpet using the stick, is there a motion for the dust particles. It is due to the inertia of rest that the dust particles move out.[152]
