When a string is divided into three segments of
lengths `l_(1),l_(2) and l_(3)` the fundamental frequencies of
these three segments are `v_(1), v_(2) and v_(3)` respectively.
The original fundamental frequency (v) of the string is

Options

A. `(1)/(v)=(1)/(v_(1)) + (1)/(v_(2))+(1)/(v_(3))`
B. `(1)/(sqrt(v)) = (1)/(sqrt(v_(1)))+(1)/(sqrt(v_(2))) + (1)/(sqrt(v_(3)))`
C. `sqrt(v) = sqrt(v_(1) +)sqrt(v_(2))+ sqrt(v_(3))`
D. `v = v_(1) + v_(2) + v_(3)`

Answer

A
