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:
\(Fy = F - 33
\)
Then, since we want the net force to be equal to zero, then:
\(F - 33 = 0
\)
From here, we clear the force that we must apply on the object:
\(F = 33
\)
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.
