  1. According to Hooke's Law, an applied force directly stretches a spring and is defined by the formula given below. F = kx Here: - F refers to the force applied - k refers to the spring constant - x refers to the extension of the spring. When the mass M is hung on the spring, the force applied is F1 =Read more

    According to Hooke’s Law, an applied force directly stretches a spring and is defined by the formula given below.

    F = kx

    Here:
    – F refers to the force applied
    – k refers to the spring constant
    – x refers to the extension of the spring.

    When the mass M is hung on the spring, the force applied is F1 = Mg where g is acceleration due to gravity and the extension is x1 = 1 cm.

    Now, if the mass is doubled to 2M then the force applied will be F2 = 2Mg, and the extension will be x2.

    By using the proportionality between force and extension:

    x2 / x1 = F2 / F1

    x2 / 1 cm = 2Mg / Mg = 2

    Therefore, the extension x2 = 2 cm.

    The correct answer is: 2 cm
