  1. Question 1

    Q1. A stone is tied to a string and rotated in a horizontal circle. If the radius is 1.5 m and its speed is 3 m/s, what is the tension?

    • A) 6 N
    • B) mv² / r
    • C) 3 N
    • D) 4 N

    Answer: mv² / r

    Explanation: Tension = mv² / r, using the formula for tension in a horizontal circle.
