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