The situation in which unbalanced forces are acting on an object is when two people stand on opposite sides of a large tire and both people push or pull the tire with equal force.
The correct answer is:
"Two people stand on opposite sides of a large tire. Both people pull the tire with equal force."
Explanation:
According to Newton's First Law of Motion, an object at rest will stay at rest and an object in motion will stay in motion with the same speed and direction unless acted upon by an unbalanced force. In this scenario, if two people are pulling the tire with equal force but in opposite directions, the forces are unbalanced. This is because the forces are acting in opposite directions and will result in a net force on the tire.
