    Answer:

    Explanation:

    For simple pendulum the formula is

    T=2\pi\sqrt{\frac{l}{g} }

    Where T is time period , l is length and g is acceleration due to gravity .

    \frac{1}{n} =2\pi\sqrt{\frac{l}{g} }

    n is frequency

    Putting the values

    \frac{1}{.4} =2\pi\sqrt{\frac{l}{10} }

    \frac{l}{10} = .1584

    l = 1.584 m
