Question

While sieving grains, small pieces fall down. Which force pulls them down?

Answer 1

Force of gravity

1. The Force of Gravity acts on small particles and pulls them down.
2. Force of gravity is the force of attraction between any objects in the universe, which is directly proportional to the masses of the objects and inversely proportional to the square distance between them.
3. The significant force of attraction is the gravitational force of the earth's mass on bodies near its surface.
4. According to Newton's law of gravitation, the force of attraction between two masses m₁ and m₂ separated by distance d is expressed as,$F=G\frac{m_{1}x{m}_2}{d^2}(whereGisgravitationalcons\tan t)$
   Hence, The Force of Gravity acts on small particles and pulls them down
