Circular Motion and Gravitation

The centripetal acceleration doubles.

The centripetal acceleration remains unchanged.

The centripetal acceleration quadruples.

The centripetal acceleration halves.

The car would increase its speed along the circular path due to a decrease in opposing frictional forces.

The car would start to slide outward because there is less frictional force available to provide the necessary centripetal acceleration.

The car would continue on its circular path with unchanged conditions as inertia alone maintains its motion.

The car's radius of curvature would decrease, leading to an increase in centripetal acceleration.

there's no friction

towards the center of the circle

It needs an inward net force because otherwise it will continue moving tangentially according to Newton’s first law

Newton's third law dictates that every action has an equal opposite reaction, thus keeping it circling.

No net force is needed for uniform motion; this follows from Newton's first Law.

A net outward force is required according to Newton's second law as acceleration points outward.

Centripetal force cannot be determined without knowing path radii.

The car with higher speed has greater centripetal force.

Both cars have equal centripetal forces since they are identical.

The car with lower speed has greater centripetal force due to less risk of slipping.

Tangentially to the circle's path.

Toward the center of the circle.

Away from the center of the circle.

In the direction of the object's velocity.
