In steel, the Young's modulus and the strain at the breaking point are $2 \times {10^{11}}\,N{m^{ - 2}}$ and $0.15$ respectively. The stress at the breaking point for steel is therefore
A$1.33 \times {10^{11}}\,N{m^{ - 2}}$
B$1.33 \times {10^{12}}\,N{m^{ - 2}}$
C$7.5 \times {10^{ - 13}}\,N{m^{ - 2}}$
D$3 \times {10^{10}}\,N{m^{ - 2}}$
