The book’s weight and the upward force the table exerts on the book have equal magnitude but opposing directions.
The correct response is:
The book’s weight and the upward force the table exerts on the book have equal magnitude but opposing directions.
The book is in a state of equilibrium because the net force acting on it is zero. In order to understand this, we need to consider the forces acting on the book.
Firstly, we know that gravity is a net force acting on the book in a downward direction. The weight of the book is the force of gravity acting on it.
Next, we consider the forces exerted by the table on the book. The table exerts an upward force on the book in order to support its weight.
To determine whether the book is in a state of equilibrium, we need to compare the magnitude and direction of these forces.
If the book is at rest on the table, it means that the book's weight and the upward force exerted by the table have equal magnitude but opposite directions. This happens because the table supports the weight of the book by exerting an upward force on it.
When the forces have equal magnitudes but opposite directions, the net force on the book is zero. If the net force is zero, the book is not accelerating or moving in any direction, and it is in a state of equilibrium.
Therefore, in this scenario, the book is in a state of equilibrium because the book's weight and the upward force exerted by the table have equal magnitudes but opposite directions.
