    Answer:

    d) decreased by a factor of the square root of 3

    Explanation:

    Data provided in the question

    Mass = M on a spring

    Spring constant = k

    Period = T

    Spring constant = 3k in the case when the same mass is hung

    Based on the above information, the period of the motion is

    As we know that

    T = 2\times Pi\times \sqrt{\frac{m}{k}}

    Based on this, there is a decrease by a factor of the square root of 3

    hence, the correct option is d.
