The fundamental frequency of a somometer...

The fundamental frequency of a somometer wire of length `l` is `f_0`. A bridge is now introduced at a distance of `trianglel` from the centre of the wire `(Delta lltltl)`. The number of beats heard if both sides of the bridges are set into vibration in their fundamental modes are `

A

`(8f_0 Delta l)/l`

B

`(f_0 Delta l)/l`

C

`(2f_0 Delta l)/l`

D

`(4f_0 Delta l)/l`
