A box with weight \( 10 \mathrm{~N} \) rests on a horizontal surface. A person pulls horizontally it with a force
\( \mathrm{P} \) of \( 3 \mathrm{~N} \) and it does not move. To start its motion,

W a second person pulls it vertically upward. If \( \mu_{\mathrm{s}}=0.5 \) and \( \mu_{\mathrm{k}}=0.3 \), then find the smallest vertical force for which the box starts moving.
(1) \( 0 \mathrm{~N} \)
(2) \( 4 \mathrm{~N} \)
(3) \( 10 \mathrm{~N} \)
(4) \( 6 \mathrm{~N} \)
