Section-C: Comprehension Type
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. The end of this string at x = 0 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 = 1.0 cm. The wave is travelling along +ve x direction.
What is the displacement of the particle of the string at x = 50 cm at time t = 0.05 s ?
