Answer:
A force of 33 N pointing upward
Explanation:
In order to have a net force of zero on the object, we must add a force that balances the original force.
We have only one force of 33 N, pointing downward. In order to balance it, we must add a force with same magnitude (33 N) but in the opposite direction (upward).
So, the force we should add is
A force of 33 N pointing upward
