The object is at rest and balanced since the forces on each side are equal and opposite (3N to the left and 3N to the right). According to Newton's first law of motion, an object at rest will remain at rest unless acted on by an unbalanced force. Since the forces are balanced in this scenario, we can conclude that the object is not accelerating horizontally, it is not stopped, and it is not slowing down to a stop rephrase like a 8th grader and shorten

The object is balanced and not moving because the forces are equal on both sides. It will stay still unless a force is applied.
