A wire is under a tension of 32N and length between the two bridges in 1m. If the length of the sample wire is 10m and its mass is 2 g, then the fundamental frequency of the wire will be

A

400Hz

B

200Hz

C

100Hz

D

800Hz

Text Solution

Verified by Experts

The correct Answer is:
B
`n=(1)/(2l) sqrt(T/m) = (1)/(2xx1) sqrt((32)/(2xx10^(-4))`
`=1/2xx4xx10^2`
`=400/2 = 200`
