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