In steel, the Young's modulus and the strain at the breaking point are  $2\times {10}^{11}{\mathrm{Nm}}^{-2}$ and 0.15 respectively. The stress at the breaking point for steel is therefore

• A

  $1.33\times {10}^{11}{\mathrm{Nm}}^{-2}$

• B

  $1.33\times {10}^{12}{\mathrm{Nm}}^{-2}$

• C

  $7.5\times {10}^{-13}{\mathrm{Nm}}^{-2}$

• D

  $3\times {10}^{10}{\mathrm{Nm}}^{-2}$
