Question

when acarpet is pulled up dust remins behind why so
​

Answer 1

Answer:

When the carpet is beaten with a stick, the stick exerts a force on the carpet which sets it in motion. The inertia of the dust particles residing on the carpet resists the change in the motion of the carpet. Therefore, the forward motion of the carpet exerts a backward force on the dust particles, setting them in motion in the opposite direction. This is why the dust comes out of the carpet when beaten.

Answer 2

Answer:

Inertia of rest

Explanation:

When we beat a carpet with a stick, a sudden unbalanced external force is applied on it and hence, it shifts from its position rapidly. The dust particles that were previously at rest on the carpet remain at rest due to their inertia and hence, get separated from the carpet. Hence your answer is inertia of rest.
