    Answer:

    a = 0.1 s b. 10 s

    Explanation:

    Given that,

    The frequency in circular motion, f = 10 Hz

    (a) Let T is the period of itsrotation. We know that,

    T = 1/f

    So,

    T = 1/10

    = 0.1 s

    (b) Frequency is number of rotations per unit time. So,

    t=\dfrac{n}{f}\\\\t=\dfrac{100}{10}\\\\t=10\ s

    Hence, this is the required solution.
