Question

Which force is used to separate solid pollutant particles from smoke given out from factories?

Answer 1

centrifugal force is used to separate the solid pollutants from smoke given out from the factories

Answer 2

Answer:

The "force" is used to "separate solid pollutant particles" from "smoke" given out from factories is Electrostatic Force.

Explanation:

In general, an electrostatic smoke precipitator uses electrostatic force, by which the solid pollutant particles, like soot, fly ash, etc. from smoke are separated out. Smoke basically behaves like an aerosol, in which, the solid pollutant particles are rubbed to produce a "small amount of electrostatic charge", at the base of the smokestack, which then is moved away from the smoke due to its charge acquisition and only the hot air comes out of the chimney of the factories.
