A transverse sinusoidal wave is generted at one end of long, horizontal string by a bar that moves up and down through a distance of `1.00 cm`. The motion is continuous and is repreated regularly `120` times per second. The string has linear density `90 gm//m` and is kept under a tension of `900 N`. Find :
What is the maximum power (in watt) transferred along the string.

A

`3.24 pi^(2)`

B

`6.48 pi^(2)`

C

`12.96 pi^(2)`

D

`25.92 pi^(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`P_(max) = 4pi^(2)f^(2)A^(2)muv = 12.96pi^(2)` watt
