What force is directed towards the center of a rotating body?

• A. Centrifugal force
• B. Centripetal force
• C. Rotational force
• D. Magnetic force

Answer: (B)

The force directed towards the center of a rotating body is known as centripetal force. This force is essential for keeping an object in a circular path by constantly pulling it towards the center of rotation. It acts perpendicular to the object's velocity and ensures that the object does not fly off in a straight line, which would occur due to inertia. Centripetal force is not a type of force in itself but rather a resultant force that can arise from various sources, such as tension in a string, gravity, or friction, depending on the context of the motion. For example, when a car turns around a bend, friction between the tires and the road provides the centripetal force that allows the car to navigate the curve. In contrast, centrifugal force is often described as a perceived force that seems to push objects outward when observed from a rotating reference frame, but it does not actually act in the way that centripetal force does. Rotational force is a more general term and does not specify the direction or nature of the force acting on a rotating body. Magnetic force pertains to the attraction or repulsion between charged particles, which is unrelated to the context of movement in a circular path.
