  1. Question 1

    Q1. A particle is moving in a circular path. If its radius is doubled and speed is doubled, what happens to its centripetal acceleration?

    • A) It is doubled
    • B) It is halved
    • C) It remains the same
    • D) It is quadrupled

    Answer: It is doubled

    Explanation: Centripetal acceleration = v² / r, so doubling v and doubling r doubles the acceleration.
