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 the 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_(i))+sqrt(n_(2))+sqrt(n_(3))`

D

`n=n_(1)+n_(2)+n_(2)+n_(3)`
