  1. Question 1

    Q1. A body is moving in a circular path with a constant speed. What is the work done by the centripetal force?

    • A) Positive
    • B) Negative
    • C) Zero
    • D) Maximum

    Answer: Zero

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