Question

While sieving grains, small pieces fall down. Which force pullsthem down?NCERT Class VIIIScience - Exemplar ProblemsChapter 11. Force

Answer 1

The process of sieving is best defined to separate much coarser material from the finer particles.

It is generally used for straining solids from liquids.

When the process of sieving is taking place, we see that small pieces are falling down which is generally due to the presence of gravitational force.

Answer 2

$\bf{Gravitational}$ force is responsible thier to bring them down.

We know that sieve have small holes from where the tiny particles can pass to get separated from undesired particles.

Hence, we can say that gravitational force is responsible for this.
