The length and diameter of a metal wire...

The length and diameter of a metal wire is doubled the fundamental frequency of vibration will change from n to (tension being kept constant and material of both the wires is same)

A

n/4

B

n/8

C

n/12

D

n/16

Text Solution

Verified by Experts

The correct Answer is:
A
`n_2/n_1 = (l_1d_1)/(l_2/d_2) sqrt((T)/(rhopi)(rhopi)/(T)) = 1/2xx1/2`
`n_2 = 1/4n_1 = n/4`
