Q. No.A metallic bar of Young's modulus \(0.5 \times 10^{11}~\text{Nm}^{-2},\) coefficient of linear thermal expansion \(10^{-5} ~^{\circ}\text{C}^{-1},\) length \(1~\text m\) and cross-sectional area \(10^{-3} ~\text{m}^2\) is heated from \(0^\circ \text{C}\) to \(100^\circ \text C\) without expansion or bending. The compressive force developed in the metallic bar is:
| 1. | \(50 \times 10^3~ \text N\) | 2. | \(100 \times 10^3 ~\text N\) |
| 3. | \(2 \times 10^3~\text N\) | 4. | \(5 \times 10^3 ~\text N\) |
