ANSWER:

0, no direction

balanced

Explanation:

We must add all the forces, the horizontal and vertical.

We must take into account the direction of the force, to the right and up are positive while to the left and down are negative.

Therefore:


\begin{gathered} F_(Rvertical)=F_n+F_g=20+(-20)=20-20=0 \\ F_{\text{Rhorizontal}}=F_{\text{app}}+F_{\text{fric}}=20+(-20)=20-20=0 \end{gathered}

Being the vertical and horizontal forces 0, the net force is 0 as it has no magnitude and no direction.

It is balanced, since the net force is 0
