On increasing the length by 0.5 mm in a steel wire of length 2 m and area of cross-section  $2{\mathrm{mm}}^2$, the force required is [Y for steel $=2.2\times {10}^{11}\mathrm{N}/{\mathrm{m}}^2]$]

• A

  $1.1\times {10}^5\mathrm{N}$

• B

  $1.1\times {10}^4\mathrm{N}$

• C

  $1.1\times {10}^3\mathrm{N}$

• D

  $1.1\times {10}^2\mathrm{N}$
