A metallic bar of Young's modulus, \(0.5 \times 10^{11}~\text{Nm}^{-2}\) and coefficient of linear thermal expansion \(10^{-5} ~^{\circ}\text{C}^{-1}\) length \(1~\text m\) and area of cross-section \(10^{-3} ~\text{m}^2\) is heated from \(0^\circ \text{C}\) to \(100^\circ \text C\) without expansion or bending. The compressive force developed in it is: 
1. \(50 \times 10^3~ \text N\)
2. \(100 \times 10^3 ~\text N\)
3. \(2 \times 10^3~\text N\)
4. \(5 \times 10^3 ~\text N\)
