Multiple choice

When milk is churned, the cream is separated due to

  1. gravitational force

  2. centrifugal force

  3. frictional force

  4. electro magnetic effect

  5. none of the above

B Correct answer
Explanation

When milk is churned, centrifugal force causes the denser components (including fat globules in cream) to separate based on density differences. Gravitational force acts uniformly and doesn't cause separation. Frictional force opposes motion, and electromagnetic effect is irrelevant to this mechanical separation process.
