Question

Which force is utilize in removing smoke particles from the effluents coming out of the chimneys of factories ?

Answer 1

Smoke is removed from the effluent before it comes out of the chimneys since it contains carbon particles which may destroy buildings.

The device used for this purpose is known as electrostatic precipitators.

Smoke particles pick up charge as they pass the charged metal grid.

The smoke particles are then attracted to oppositely charged collecting plates.

The force used is ELECTROSTATIC FORCE.
