<p>A wire of cross sectional area A, modulus of elasticity&nbsp;<span class="equation">\(2\times10^{11}Nm^{-2}\)</span>&nbsp;and length 2m&nbsp; is stretched between two vertical rigid supports. When a mass of 2 kg&nbsp; is suspended at the middle it sags lower from its original position making angle&nbsp;<span class="equation">\(\theta = \frac{1}{100}\)</span>&nbsp;radian on the points of support. The value of&nbsp; A is_______<span class="equation">\(\times 10^{-4}m^2\)</span>&nbsp;(consider x &lt; &lt; L).</p>

<p>(given : g = 10&nbsp;<span class="equation">\(m/s^2\)</span>)​​​​​​​</p>
