Answer:
3N not 0N (first blank)
3N (second blank)
0N (third blank)
Explanation:
1st blank - If a force equals 0, it is balanced.
2nd blank - If one force of 3 Newtons is pushing to the left and another force of 3 Newtons is pushing from the right it wouldn't go anywhere, so it would be balanced at zero.
3rd blank - It would be 0N because forces of the same amount pushing opposite directions would be balanced.
