The correct response is: The book’s weight and the upward force the table exerts on the book have equal magnitude but opposing directions.
In a state of equilibrium, the forces acting on an object are balanced. In this case, the weight of the book (a downward force due to gravity) is equal in magnitude to the normal force exerted by the table (an upward force). These forces are equal and opposite, resulting in a net force of zero, which is why the book remains at rest on the table.
