A block of mass $\displaystyle 5$ kg is placed on a rough inclined surface as shown in the figure. If $\displaystyle \overrightarrow{F_1}$ is the force required to just move the block up the inclined plane and $\displaystyle \overrightarrow{F_2}$ is the force required to just prevent the block from sliding down, then the value of $\displaystyle \left|\overrightarrow{F_1}\right|-\left|\overrightarrow{F_2}\right|$ is: $\displaystyle \left[\right.$ Use $\displaystyle \left.\mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2\right]$
