A block of mass $\displaystyle 5$ kg is moving on an inclined plane which makes an angle of $\displaystyle 30^{\circ}$ with the horizontal. Friction coefficient between the block and inclined plane surface is $\displaystyle \frac{\sqrt{3}}{2}$. The force to be applied on the block so that the block will move down without acceleration is $\displaystyle \_\_\_\_$ N.
$\displaystyle \left(g=10 \mathrm{~m} / \mathrm{s}^2\right)$.
