In the figure, horizontal force $$\overrightarrow{F_1}$$ of magnitude $$10\mathrm{N}$$ is applied to a box on a floor, but the box does not slide. Answer the following questions as the magnitude of vertical force $$\overrightarrow{F_2}$$ is increased from zero. Does the magnltude of the frictional force on the box $$\overrightarrow{f_3}$$ increase, decrease or stay the same? Increase Stays the same Decrease Does the magnitude of the normal force $$\overrightarrow{F_N}$$ on the box from the floor increase, decrease or stay the same? Increase Stays the same Decrease Does the maximum value $$f_{s\max }$$ of the magnitude of the static frictional force on the box increase, decrease or stay the same? Increase Stays the same Decrease Does the box eventually slide? Yes
