If `n_(1),n_(2) and n_(3)` are the fundamental frequencies of three segments into which a string is divided, then the original fundamental frequency n of string is given by

A

`(1)/(n)=(1)/(n_1) + (1)/(n_2) + (1)/(n_3)`

B

`(1)/(sqrt(n))=(1)/(sqrt(n_1)) + (1)/(sqrt(n_2)) + (1)/(sqrt(n_3))`

C

`sqrt(n)=sqrt(n_1) + sqrt(n_2) + sqrt(n_3)`

D

`n=n_1 + n_2 + n_3 `
