  1. Question 1

    Q1. A body is moving in a circular path. If its speed is doubled, what happens to the centripetal force?

    • A) It becomes 2 times
    • B) It becomes 4 times
    • C) It becomes 8 times
    • D) It remains the same

    Answer: It becomes 4 times

    Explanation: New F = m * (2v)² / r = 4 * mv²/r, so it becomes 4 times, using F = mv²/r.
