In which situation are unbalanced forces acting on an object?

a Two people stand on the same side of a large tire. Both people pull the tire with equal force.
b 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.
c Two people stand on opposite sides of a large tire. Both people pull the tire with equal force.
d Two people stand on opposite sides of a large tire. Both people push the tire with equal force.

d Two people stand on opposite sides of a large tire. Both people push the tire with equal force.

The situation in which unbalanced forces are acting on an object is option b: 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 scenario, the forces are not balanced because one person is pushing and the other person is pulling. As a result, the tire will experience a net force and will start to move in the direction of the greater force.

The situation where unbalanced forces are acting on an object is option (b) 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.

Explanation:

When two people stand on the same side of a large tire and one person pushes the tire while the other pulls it with equal force, the forces being applied are unbalanced. This is because the forces are acting in different directions - one force is pushing and the other force is pulling.

To determine if the forces are balanced or unbalanced, you need to compare the magnitudes and directions of the forces being applied to the object. If the forces are equal in magnitude and opposite in direction, they are balanced and the object will not accelerate. However, if the forces are equal in magnitude but act in different directions, the forces are unbalanced and the object will experience a net force, causing it to accelerate.
