    A very light rod connects two masses, m1and m2. The rod is to be suspended by a string so that it hangs horizontally. Given that the length of the rod is D = 63.0 cm, find the appropriate position of the string (the distance x, as shown in the figure) for each of the following cases.
    (a) m1 = 0.81 kg and m2 = 0.81 kg
    (b) m1 = 0.81 kg and m2 = 0.39 kg

    (Please see the attached Question File for complete description).
