A block of mass $5 \mathrm{kg}$ is placed on a rough inclined surface as shown in the figure. If ${\overrightarrow{F}}_1$ is the force required to just move the block up the inclined plane and ${\overrightarrow{F}}_2$ is the force required to just prevent the block from sliding down, then the value of $\left|{\overrightarrow{F}}_1\right|-\left|{\overrightarrow{F}}_2\right|$ is: [Use $g=10 \mathrm{m} {\mathrm{s}}^{-2}$]
