Problem

Two strings, A and B, are stretched between rigid supports and are under the same initial tension of

120\,\text{N}

. • String A: length

0.80\,\text{m}

, linear mass density

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

• String B: length

0.60\,\text{m}

, linear mass density

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

(i) Frequency ratio of fundamentals. (ii) Identify higher pitch. (iii) New tension in string B for equal frequencies.
