An ideal string of length \(1.20\) m is fixed at both ends. It vibrates in its third harmonic with a frequency of \(180\) Hz when the tension in the string is \(80\) N. If the tension is increased by \(25\%\), the frequency rises to \(1.12\) times its original value. Determine the linear mass density of the string in kg m\(^{-1}\) (give your answer to three significant figures).

A. 3.45×10⁻³ kg m⁻¹

Correct Answer B. 3.86×10⁻³ kg m⁻¹

C. 2.98×10⁻³ kg m⁻¹

D. 4.12×10⁻³ kg m⁻¹

Correct Answer

Correct Option:

3.86×10⁻³ kg m⁻¹
