Concept:In uniform circular motion, the speed of the particle remains constant, but its velocity direction changes continuously.Explanation:The linear velocity v at any instant is always tangential to the circular path.The magnitude of v, which is the speed, does not change in uniform circular motion.So the linear velocity is tangential with constant magnitude.The acceleration is centripetal, directed radially inward toward the center of the circle.It is not tangential to the circle, nor is it along the axis of the circular path.Thus, option A is wrong because velocity is not radial.Options C and D are wrong because linear acceleration is radial, not tangential or axial.Therefore, the only correct statement is option B.Answer:Option B: linear velocity always tangential to the circular path, without change in its magnitude.
