Unbalanced forces are acting on an object when the net force is not zero, meaning that the forces acting on the object do not cancel each other out. In the given scenarios, the situation where unbalanced forces act on the tire is:
Two people stand on the same side of a large tire. One person pushes the tire and the other pulls the tire with equal force.
In this case, because one person is pushing and the other is pulling, the forces act in opposite directions, which would create a net force on the tire, causing it to move or accelerate in the direction of the stronger force, assuming they are equal. The other options describe balanced forces, where forces cancel each other out.
