<p>Two metallic wires P and Q have same volume and are&nbsp;made up of same material. If their area of cross sections are in the ratio 4 : 1 and force&nbsp;<span class="equation">\(F_1\)</span>&nbsp;is applied to P, and extension of ​​​​​​​<span class="equation">\(\triangle\)</span>l is produce. The force which is required to produce same extension in Q is <span class="equation">\(F_2\)</span>​​​​​​​</p>

<p>The value of&nbsp;<span class="equation">\(\frac{F_1}{F_2}\)</span>&nbsp;is_____​​​​​​​</p>
