For this case, the first thing we are going to do is define a reference system.
We define the vertical axis of the reference system, pointing upwards.
Therefore, doing summation of forces in vertical direction we have:
[tex] Fy = F - 33
[/tex]
Then, since we want the net force to be equal to zero, then:
[tex] F - 33 = 0
[/tex]
From here, we clear the force that we must apply on the object:
[tex] F = 33
[/tex]
The positive sign means that the force points upwards.
Answer:
to create a net force of zero on the object you must apply:
33 Newton upwards.
