  1. Question 1

    Q1. What is the work done by the centripetal force on a particle moving in a circular path?

    • A) Positive
    • B) Negative
    • C) Zero
    • D) Depends on the radius

    Answer: Zero

    Explanation: Centripetal force is perpendicular to displacement, so work done is zero, given by W = F * d * cos(90°) = 0.
