Cream gets separated out of milk when it is churned. This is due to– (1) gravitational force (2) centripetal force (3) centrifugal force (4) frictional force

1 Answer

Answer :

(3) centrifugal force Explanation: During the churning of buttermilk, many particles of curd undergo rotatory motion: Then the particles with less weight experience more centripetal force and hence those particles accumulate at the center. Heavier particles experience more centrifugal force and so they are forced to the walls of the container away from the centre.
