When a string is divided into three segments of length `l_1,l_2` and `l_3` the fundamental frequencies of these three segments are `f_1,f_2` and `f_3` respectively. The original fundamental frequency `f` of the string is

A

`sqrt(v)=sqrt(v_1)+sqrt(v_2)+sqrt(v_3)`

B

`v= v_1 +v_2+v_3`

C

`1/v=1/v_1+1/v_2+1/v_3`

D

`1/sqrt(v)=1/sqrt(v_1)+1/sqrt(v_2)+1/sqrt(v_3)`
