A string of length $l$ is fixed at both ends. It is vibrating in its 3rd overtone with maximum amplitude $a$ . The amplitude at a distance $l /3$ from one end is:

Options:

Answer:

Solution:

The 3rd overtone is the 4th harmonic, with amplitude $a sin (4 π x / l)$ . At $x = l /3$ : $sin (4 π /3)$ has magnitude $3 /2$ , so the amplitude is $3 a /2$ .
