When milk is churned, cream gets separated due to (a) centripetal force (b) centrifugal force (c) fricitional force (d) gravitational force

Answer: (b). In the rotating frame of the churner, every particle feels an outward centrifugal force mω² r. Heavier milk particles are pushed outward more; the lighter cream collects near the axis. So the answer is (b) centrifugal force.

When milk is churned, cream gets separated due to

Show answer and solution

Answer: (b)

In the rotating frame of the churner, every particle feels an outward centrifugal force $m\omega^2 r$ .
Heavier milk particles are pushed outward more; the lighter cream collects near the axis.
So the answer is (b) centrifugal force.
