Concept:In uniform circular motion, the linear velocity v always acts along the tangent to the circle at the object’s position, not along the radius.Explanation:The object moves with a constant speed, so the magnitude of v is fixed.However, the direction of v changes continuously as the object moves around the circle.At any instant, v must be tangential to the circular path and must point in the same direction as the object is moving.From the diagram, the arrow that is tangent to the circle at the object and points along the direction of motion is arrow X.The other arrows are either radial or point in directions that do not represent the motion.Therefore, the linear velocity is indicated by the tangent arrow X.Answer:Option B: X
