Question

Cleaning of dust from carpet is due to _____.

• A. Inertia of motion
• B. Inertia of rest
• C. Inertia of direction
• D. Momentum

Answer 1

Answer: (B)

Inertia of rest

Cleaning of dust from the carpet is due to the inertia of rest that the particle tends to remain at rest if no external force is applied to it.

When we beat a carpet with the help of a stick, the carpet comes into a motion whereas the dust particle remain at rest due to their inertia of rest and hence get separated out of the carpet.
