Academics

In the arrangement shown in the figure below, an object of mass 4.2 kg hangs from a cord around a light pulley. The length of the cord between point P and the pulley is 3.5 m. When the vibrator is set to frequency of 183 Hz, a standing wave with eighteen loops is formed.

(a) How many complete loops (if any) will result if the mass is changed to 16.8 kg? (Answer with -100 if no standing wave forms.)
