Answer : 3. "केन्द्रापसारी बल"
Explanation :

When milk is churned, the cream is separated from it due to centrifugal force because this force acts in an outwards direction. Due to this outward force, the heavier particles in milk experience more force than the lighter particles. The cream part, being heavier, separates from the milk and gets churned out.
