7. A 4.50 kg block is pressed against a vertical wall by a force (→F), as shown in the figure below. The coefficient of static friction between the block and the wall is 0.32 and the directional angle θ for the force is 46°. Determine the magnitude of the force (→F) when the block is about to slide up the wall.
