Which example indicates that forces acting on an object are balanced?
A book lying motionless on a shelf
When the forces acting on an object are balanced, its state of motion does not change; a book lying motionless on a shelf experiences balanced gravitational and normal forces.
Hence, the correct answer is A book lying motionless on a shelf.
