Answer:
reaction force is 3N
Explanation:
The question is not complete.
From estudyassistant, I've gathered that the action force pushing the air out of the balloon is -3N.
Now,from Newton's third law of motion, it says, for every action, there is an equal and opposite reaction.
Thus, the reaction force will be equal and opposite in direction to the action force.
Thus, reaction force is 3N
