In a state of equilibrium, the forces acting on the book are balanced. This means that the upward force (the normal force from the table) is equal in magnitude and opposite in direction to the downward force (the weight of the book due to gravity). Therefore, the net force acting on the book is zero, which allows it to remain at rest on the table.
