Action and reaction
A nonexample of force would be an object at rest with no external forces acting upon it. For example, a book sitting on a table with no one pushing or pulling on it would be a nonexample of force.
Yes, if a book is stationary on a table, the forces acting on it are in equilibrium. The resultant force acting on the book would be zero, as the forces are balanced and there is no net force causing any acceleration or movement.
The book is experiencing a gravitational force pulling it downward towards the Earth, and a normal force exerted by the table pushing upward to support the weight of the book. These two forces are balanced, resulting in the book being at rest on the table.
A stationary object does not move due to force acting upon it. For example, a book sitting on a table will remain stationary until a force is applied to it, such as someone picking it up or pushing it.
The main forces acting on a chair are gravity, which pulls the chair downward towards the Earth, and the normal force exerted by the floor or supporting surface, which balances the force of gravity to keep the chair in place. Other forces could include friction between the chair and the floor, as well as any additional forces such as those applied by a person sitting on the chair.

The book sitting on the table until it is moved is described by Newton's First Law of Motion, also known as the law of inertia. This law states that an object at rest will remain at rest, and an object in motion will remain in motion with a constant velocity unless acted upon by an external force.
A stationary object does not move due to force acting upon it. For example, a book sitting on a table will remain stationary until a force is applied to it, such as someone picking it up or pushing it.
Gravity, Air resistence, friction and the push from the floor/table
No. If the book is sliding along the table, then there must be some external force being applied to the book to cause the movement. You pushed the book and created a force to move. And this is exactly what the first law is saying- a body at rest (net forces acting on book=0) remains at rest unless acted upon my some external force.
The Net external forces is the result force of two objects acting upon it. So if like two forces act on a book. One force exerts downward on the book and the other force pushes the table back on the book with the same amount of push and pull. Since both forces are pushing on each other with the same amount of energy the resultant force or net external force will be in equilibrium or zero.
A chair you sit upon, and a table you eat upon.
Tension and compression are the two forces that act upon a bridge.
