A long string having a cross-sectional area 0.80 mm2 and density 12.5 g/cm3 is subjected to a tension of 64 N along the x-axis. One end (at x = 0) of this string is attached to a vibrator moving in transverse direction at a frequency of 20 Hz.
At, t = 0, the source is at a maximum displacement y = 1.0cm.
Find the speed of the wave travelling on the string.
- 20 m/s
- 10 m/s
- 80 m/s
- 40 m/s
Answer
(C) 80 m/s
