Correct answer and explanation
Correct answer: V2/r
Explanation: ā Correct Answer: C) V2/r š Explanation: Even though the particle is moving at a constant speed, its direction of motion is changing at every single point along the circular path. This constant change in velocity direction means the particle is constantly accelerating toward the center of the circle. The magnitude of this centripetal acceleration is strictly given by the formula a = V2/r
