  1. Question 1

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

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

    Answer: It is doubled

    Explanation: Centripetal acceleration is inversely proportional to r, so when r is halved, a is doubled.
