  1. Question 1

    Q1. A stone is tied to a string and rotated in a horizontal circle at 6 m/s. If the radius is 3 m, what is the tension?

    • A) 10 N
    • B) 12 N
    • C) 15 N
    • D) 20 N

    Answer: 12 N

    Explanation: Tension = (m * v²) / r. Assuming m = 1 kg, Tension = (1 * 6²) / 3 = 12 N.
