A person pulls a block by applying a force \( \mathrm{F} \) and the block remains at rest. The arrows in the
P diagram correctly show the directions, but not

W necessarily the magnitudes, of the various forces on the block. Which of the following relations among the force magnitudes \( \mathrm{F}, \mathrm{W}, \mathrm{N} \), and f must be true? Here \( \mathrm{f} \) is friction and \( \mathrm{W} \) is the weight (the force of gravity), and \( \mathrm{N} \) is the normal reaction.
(1) \( \mathrm{F}=\mathrm{f} \) and \( \mathrm{N}=\mathrm{W} \)
(2) \( F=f \) and \( NW \)
(3) \( \mathrm{F} \) f and \( \mathrm{N}\mathrm{W} \)
(4) F \( \) f and \( N=W \)
