Question

When a carpet is beaten with a stick, dust particles come out due to

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

Answer 1

The correct option is A Inertia of rest

Initially, the dust particles are at rest along with the carpet. When the carpet is being beaten with a stick, the carpet moves but the dust particles remain at rest due to inertia of rest. Thus, the dust gets detached from the carpet.
Hence, the correct answer is option (1).
