Solution
The correct option is C Both the statements are true. Rest and motion changes for an object with respect to the point of view or reference frame. For example- For a person travelling in a bus, to him all other passengers including him are at rest with bus as the frame of reference. However for a person who's outside the bus, sees everyone inside the bus in motion.
The motion of objects such that all its points are in a circular path about a point is known as rotational motion. In the case of the switched on table fan, the blades of the fan follow rotational motion.
