The fundamental frequency of string stretched with a weight of 16kg is 512 Hz. The weight required to produce its octave is

A

4 kg wt

B

12kg wt

C

64 kg wt

D

24 kg wt

Text Solution

Verified by Experts

The correct Answer is:
C

`n_2/n_1 = sqrt(T_2/T_1)`
`(2n_1)/(n_1) = sqrt(T_2/T_1)`
`therefore T_2=4T_1`
`=4xx16 = 64` kg wt
