Answer:
C) directed toward the center of the circle.
Explanation:
An object undergoing uniform circular motion is an object that is moving at constant speed along a circular trajectory.
According to Newton's Laws, in order to keep the object in circular motion, there must be a net force that keeps changing the object's direction (otherwise, the object would just move in a straight path due to its inertia).
This force is called centripetal force, and it always points towards the centre of the circular path. Its magnitude is given by
where
m is the mass of the object
v is the speed
r is the distance of the object from the centre of the trajectory
