  1. Question 1

    Q1. A stone is tied to a 1 m long string and rotated in a horizontal circle at 2 rev/s. What is the tension?

    • A) 16π² N
    • B) 8π² N
    • C) 4π² N
    • D) 2π² N

    Answer: 16π² N

    Explanation: Tension = m * ω² * r = 1 * (2 * 2 * π)² * 1 = 16π² N, using T = mω²r.
