Problem

A sonometer wire

1.0\,\text{m}

long has tension

100\,\text{N}

and linear mass density

1.0\times10^{-3}\,\text{kg\,m}^{-1}

. What will be its fundamental frequency after the tension is increased to

400\,\text{N}

(length and linear density unchanged)? a)

158\,\text{Hz}

79\,\text{Hz}

316\,\text{Hz}

632\,\text{Hz}
