Under the same load, wire A having length

5.0 \mathrm{~m}

and cross section

2.5 \times 10^{-5} \mathrm{~m}^{2}

stretches uniformly by the same amount as another wire B of length

6.0 \mathrm{~m}

and a cross section of

3.0 \times 10^{-5}

\mathrm{m}^{2}

stretches. The ratio of the Young's modulus of wire A to that of wire

B

will be :
