Physics - Heat & Thermo Question with Solution | TestHub

The pressure that has to be applied to the ends of a steel wire of length 10 cm to keep its length constant when its temperature is raised by $100^{\circ }\mathrm{C}$ is $\frac{11}{\mathrm{N}}\times 10^8\mathrm{Pa}$ then N is (For steel Young's modulus is $2\times 10^{11}{\mathrm{Nm}}^{-2}$ and coefficient of thermal expansion is $1.1\times 10^{-5}{\mathrm{K}}^{-1}$ )
