  1. Question 1

    Q1. A stone is tied to a 1 m long string and rotated in a vertical circle. What is the minimum speed at the top?

    • A) √10 m/s
    • B) √5 m/s
    • C) 3 m/s
    • D) 4 m/s

    Answer: √10 m/s

    Explanation: v = √(g*r) = √(10*1) = √10 m/s, using the formula for minimum speed at the top.
