A string of mass 2.50kg is under a tension os 200N. The length of the stretched string is 20.0m. If the transverse jerk is struck at one end of the string, how long does the disturbance take to reach the other end?

A

1 s

B

`0.5` s

C

2 s

D

Data insufficient

Text Solution

Verified by Experts

The correct Answer is:
b
Here, `m = (2.5)/20 "kgm"^(-1)`, T = 200 N
`v=sqrt(T/m)=sqrt(200/(2.5//20))=200/5 = 40"ms" ^(-1)`
Time taken , `t = l/v= 20 /40 = 0.5 s`

A uniform string of length 6.5 m is subjected to a tension of 40 N . Mass of the string is 162.5 g . One end of the string is fixed and the other end is tied to a source (s). which produces a transverse oscillation. The displacement of the end of the string tied to the source can be expressed as y = (3 mm) sin (40 pi t) , where ‘t’ is time. Find the displacement of point P of the string at a distance of 3.75 m from the fixed end, at time t = 0.3 s .
