The correct choice refers to the outward force experienced by particles in circular motion when they are released. Centrifugal force is perceived as the force that acts outward on a body moving around a center, arising from the body's inertia. In a circular motion context, while an object is being moved in a curved path, it wants to continue in a straight line. When the force that keeps it moving in a circle is no longer applied (for example, when the object is released), it appears to experience an outward force from the perspective of the rotating frame.

Understanding centrifugal force helps in various contexts, including physics and engineering, where analyzing motion in circular paths is crucial. This force is not a true force acting on the object as it would be in Newtonian physics, but rather a result of the object's inertia in the rotating reference frame.

The other options do not describe this phenomenon accurately. Gravitational pull pertains to the attraction between masses. Centripetal force is the actual force acting on an object moving in a circular path that keeps it in that path, directed towards the center of the circle. Frictional force is the resistance encountered when two surfaces slide against each other. None of these relate to the perceived outward force experienced when an object is released
