{'cream separation becuase': [0, 0, 1, 0], 'milk': [0, 0, 1, 2], 'cohesive force': [0, 0, 1, 0], 'fat': [1, 1, 1, 0], 'centrifugal force': [0, 0, 1, 0], 'gravitational force': [0, 0, 0, 6], 'centripetal force': [0, 0, 1, 2]}

In a cream separation process, the fat can be separated from milk due to the centrifugal force.

Cohesive force (option 1) refers to the force that holds particles of the same substance together. While cohesive forces may exist within the milk, they are not responsible for the separation of fat from milk. Therefore, option 1 is incorrect.

Gravitational force (option 2) is the force that pulls objects towards the center of the earth. While gravity plays a role in the separation process, it is not directly involved in the separation of fat from milk. Hence, option 2 is incorrect.

Centrifugal force (option 3) is the force that is exerted on an object moving in a circular path. In cream separation, the milk is subjected to centrifugal force, which causes the denser fat particles to move towards the outer edge of the container, while the lighter components of the milk remain in the center. This separation occurs due to the difference in densities between the fat and the rest of the milk. Thus, option 3 is the correct answer.

Centripetal force (option 4) is another force that acts towards the center of a circular path. However, in the context of cream separation, it is centrif
