Answer:
The direction of centripetal force is always orthogonal to the motion of object.
Step-by-step explanation:
Centripetal force is force which compels an object to move in the circular path with the constant speed. The direction of velocity of object is always tangent to the circular path. Because in circular motion, it is important to maintain constant speed so, object can only be accelerated by changing the direction of velocity. The direction of velocity can only be changed if the direction of centripetal force is perpendicular to motion of the object (towards center).
