The funduamental frequency of a sonometer wire of length l is `n_(0)`. A bridge is now introduced at a distance of `Deltal(ltltl)` from the centre of the wire. The lengths of wire on the two sides of the bridge are now vibrated in their fundamental modes. Then, the beat frequency is nearly

A

`n_(0)(Deltal)//l`

B

`8n_(0)(Deltal)//l`

C

`2n_(0)(Deltal)//l`
