Question

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

• A. the inertia of rest keeps the dust in its position and the dust is removed when the carpet moves away.
  
• B. the inertia of motion removes dust.
• C. no inertia involved in process.
• D. jerk compensates for the force of adhesion between dust and carpet and dust is removed.

Answer 1

The correct option is A the inertia of rest keeps the dust in its position and the dust is removed when the carpet moves away.

While dusting we give a sudden serk our beat with stick because when we do that stick because when we do that the particle of carpet move with our help and the dust particle stays at rest by inertia and eventually they separate from the carpet.
