Wired Faculty App

Dust generally settles down in a closed room. Explain.

Solution

Dust particle are very small spherical particles. Now, using the formula of terminal velocity,

v ∝ r²The small dust particles acquire a very small terminal velocity and remain suspended in air because of their small size. Therefore, they will settle down in a closed room after some time.
