The tension in a sonometer wire is increased to nine times. Then the fundamental frequency of the wire is

A

9 times

B

3 times

C

1/3 times

D

1/9 times

Text Solution

Verified by Experts

The correct Answer is:
B
`n_1 prop sqrt(T) " and " n_2 prop sqrt(T_2)`
`therefore n_2/n_1 = sqrt(T_2/T_1) = sqrt(T_1/T_1) therefore n_2=3n_1`
