* Forces:

* Gravity (downward): 35 N

* You (upward): 39 N

* Net Force: To find the net force, we subtract the smaller force from the larger force.

* Calculation: 39 N (upward) - 35 N (downward) = 4 N

* Answer: The net force is 4 N upward. This means the box will accelerate upward because the force you're applying is greater than the force of gravity pulling it down.
