Hi.. I need a good explanation for the following question. an explanation with a small mathematical calculation to prove the answer would be highly helpful.(adsbygoogle = window.adsbygoogle || []).push({});

A copper rod of cross-section 10 mm 10 mm is stretched along its axis, changing length from 1.000 m to 1.001 m. The deformation is elastic, or fully recoverable. Given that the modulus of copper is 110 GPa, the stress on the rod is approximately (choose the closest answer):

A 110 kPa

B 110 MPa

C 110 GPa

D 1/110 MPa

E 1/110 GPa

thanks in advance!
