Which of the following situations represents balanced force?
Two people push a box from opposite sides with equal force.
Forces are balanced when the net force on an object is zero, meaning all forces cancel each other out and the object remains in its current state (rest or uniform motion).
When two people push a box from opposite sides with equal force, the two forces are equal in magnitude and opposite in direction — they cancel exactly. The net force on the box is zero: this is balanced force. A ball in free fall has only gravity acting on it (unbalanced). A braking car has an unbalanced friction force. A cyclist going uphill has an unbalanced net force pulling them back.
The correct answer is : Two people push a box from opposite sides with equal force.
