A rod is fixed between two points at $20°C$. The coefficient of linear expansion of material of rod is $1.1 \times {10^{ - 5}}/^\circ C$ and Young's modulus is $1.2 \times {10^{11}}\,N/m$. Find the stress developed in the rod if temperature of rod becomes $10°C$

  • C

    $1.32 \times {10^8}\,N/{m^2}$

  • D

    $1.10 \times {10^6}\,N/{m^2}$
