  1. Question 1

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

    • A) It becomes half
    • B) It remains the same
    • C) It becomes double
    • D) It becomes 1/4

    Answer: It becomes half

    Explanation: Centripetal acceleration is given by a = v² / r. If r is doubled, a becomes half.
