Question

While dusting a carpet, we give a sudden jerk or beat with a stick because :

• A. Inertia of rest keeps the dust in its position and the dust is removed by movement of carpet away.
• B. Inertia of motion removes dust.
• C. No inertia involved in process.
• D. None of the above

Answer 1

The correct option is A Inertia of rest keeps the dust in its position and the dust is removed by movement of carpet away.

When carpet is given sudden jerk, due to inertia dust particles does not change position, while carpet moves.

Thus dust particles gets separated from carpet.

So, Option A is correct.
