A ball on a string is travelling in circular motion. Which vector represents the centripetal force?

• The green vector because it points towards the center of the circular path
• The blue vector because it shows the direction of the object's inertia
• The green vector because it shows the path of the ball
• The blue vector because this is the way the ball will move when it is released.
