Figure shows a steel rod of cross sectional ara `2 xx 10^(-6)m^(2)` is fixed between two vertical walls. Initially at `20^(@)C` there is no force between the ends of the rod and the walls. Find the force which the rod will exert on walls at `100^(@) C`. Given that the coefficient of linear expansion of steel is `1.2 xx 10^(-5).^(@)C^(-1)` and Young's modulus is `2xx10^(11)N//m^(2)`
