A block kept on a rough inclined plane, as shown in the figure, remains at rest upto a maximum force $\displaystyle 2$ N down the inclined plane. The maximum external force up the inclined plane that does not move the block is $\displaystyle 10$ N. The coefficient of static friction between the block and the plane is :
[Take $\displaystyle \mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2$ ]
