### Step-by-Step Solution:
1. **Understanding Centrifugal Force**:
- Centrifugal force is often described in the context of circular motion. It is the apparent force that seems to act outward on a mass moving in a circular path, away from the center of rotation.
2. **Identifying the Nature of Centrifugal Force**:
- It is important to note that centrifugal force is not a real force. Instead, it is considered a fictitious or pseudo force. This means it does not arise from any physical interaction but rather from the inertia of the object in circular motion.

(a) How does a centripetal force differ from a centrifugal force with reference to the direction in which they act? (b) Is centrifugal force the force of reaction of the centripetal force? ( c) compare the magnitudes of centripetal and centrifugal force.
Match list I with list II LIST - I (a) Centrifugal force (b) Centripetal force (c ) Tangential force (d) Angular velocity LIST - II (e ) Along the axis of rotation (f) Towards the centre of rotation (g) Away from the centre of rotation (h) Changes the angular velocity
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.
Centripetal and Centrifugal Force
Compare the magnitudes of centripetal and centrifugal force.
State two differences between centripetal and centrifugal force.
Is centrifugal force a real force?
Is centrifugal force the force of reaction of centripetal force ?
A : The centripetal and centrifugal forces never cancel each other. R : They are action and reaction forces.
Assertion: The centripetal forces and centrifugal forces never cancel out. Reason: They do not act at the same time.
