<p>A particle of mass m, moving along a straight line, experiences a force F which varies with the distance travelled as shown in the figure. If the velocity of the particle at&nbsp;<span class="equation">\(x_0\)</span>&nbsp;is&nbsp;<span class="equation">\(\sqrt{{2F_0}x_0 \over m}\)</span>,&nbsp;then, velocity at&nbsp;<span class="equation">\(4x_0\)</span>&nbsp;is,</p>
