(II) One end of a horizontal string is attached to a small-amplitude mechanical 60.0-Hz oscillator. The string's massper unit length is 3.5 × 104 kg/m. The string passes over apulley, a distancel = 1.50 m away, and weights are hungfrom this end, Fig. 11–55. What mass m must be hung fromthis end of the string to produce (a) one loop, (b) two loops,and (c) five loops of a standing wave? Assume the stringat the oscillator is a node, which is nearly true.-1.50 m-OscillatormFIGURE 11-55 Problems 55 and 56.
