369655 A metallic rod breaks when strain produced is \(0.2 \%\). The Young's modulus of the material of the rod is \(7 \times {10^9}\;N{\rm{/}}{m^2}\). What should be its area of cross-section to support a load of \({10^4}\;N\)?

1 \(7.1 \times {10^{ - 8}}\;{m^2}\)
2 \(7.1 \times {10^{ - 6}}\;{m^2}\)
3 \(7.1 \times {10^{ - 4}}\;{m^2}\)
4 \(7.1 \times {10^{ - 2}}\;{m^2}\)
