  1. Question 1

    Q1. A stone is tied to a string and whirled in a horizontal circle. If the mass is doubled, what will be the effect on the centripetal force?

    • A) Doubled
    • B) Halved
    • C) Remains the same
    • D) Quadrupled

    Answer: Doubled

    Explanation: The centripetal force is given by F = (m * v²) / r, so doubling the mass will double the force.
