Some washing machines have cloth driers. It contains a drum in which wet clothes are kept. As the drum rotates, the water particles get separated from the cloth. The general description of this action is that "the centrifugal force throws the water particles away from the drum". Comment on this statement from the viewpoint of an observer rotating with the drum and the observer who is washing the clothes.
Answers
Answer ⇒ If I will sit in the drum rotating with the clothes, then I will be in the Non-Inertial Frame. We know that Newton's law of the motion are only valid in inertial Frame. Therefore, to make them valid in Non-Inertial Frame, we apply the Pseudo force in opposite direction.
Therefore, The Pseudo force in the form of the Centrifugal force will be acting on the water particles which will force them to get out. This means hat Statement is 100 % true from the view point of an observers rotating with the drum.
But This statement cannot be true from the point of view of the Person washing the clothes. This is because the person who will be watching this from outside will be in Inertial frame. So, there will be no pseudo force. Hence, Centripetal force will be acting innards. But since, it is unable to balanced thus the water particles will move always from it by Inertial force.
Hope it helps.
