NINE FIVE RUPEE COINS ARE PUT ON TOP OF EACH OTHER ON A TABLE.EACH COIN HAS A MASS m kg .THE REACTION OF THE FIFTH COIN(COUNTED FROM BOTTOM)ON SIXTH COIN IS.
4mg as there are invited4 coins above the 5th coin from bottom.
Why when a hanging carpet is beaten with a stick, the dust particles start coming out of it?
Please explain to me, in a simple language.
Asked Osho Garg
This is due to the inertia of rest of the dust particles.
When the mat is beaten suddenly with a stick, the mat moves forward, but the dust tends to remain at the same position on account of the inertia of rest. When the mat/ carpet moves, the dust particles lose support and they fall down

Newton’s Third Law of Motion states that
“Every action has equal and opposite reaction”
In other words,
“Whenever a body exerts a force on another body, the second body exerts an equal and opposite force on the first body”
Osho Garg asks:
“if a person is sitting on a chair both the chair and person exert force against it so we called that ” there is always an equal and opposite reaction ” but for example a elephant of mass 584 kg sit on a chair, the chair will broke. So what we called for this . Please explain.
When an elephant “sits” on a chair, it breaks because it cannot give the “equal reaction” and it “yields” to it.
Therefore, here the force is doing “work”.
More discussions are welcome
