उत्तर
When a carpet is beaten with a stick, then carpet comes in motion but dust particles present on them try to remain at rest because of inertia of rest and hence the dust fly off. Strong winds slake the branches of a tree, laden with fruits, vigorously. As a result, branches come in motion but fruits try to remain at rest due to inertia of rest and hence get detached from the tree and fall off.
