<p>A steel rod of length 1m&nbsp; and cross sectional area&nbsp;<span class="equation">\(10^{-4}m^2\)</span>&nbsp;is heated from <span class="equation">\(0^0C \)</span>&nbsp;to <span class="equation">\( 200^0C \)</span>&nbsp;without being allowed to extend or bend. The compressive tension produced in the rod is ___________&nbsp;<span class="equation">\(\times10^4\)</span>N. &nbsp;(Given Young&#39;s modulus of steel = <span class="equation">\(2\times 10^{11}Nm^{-2}\)</span>, coefficient of linear expansion = <span class="equation">\(10^{-5}K^{-1}\)</span>)​​​​​​​​​​​​​​​​​​​​​</p>
