Why is a book resting on a table in a state of equilibrium?(1 point)
Responses
The book and the table have the same weight.
Gravity is a net force acting on the book in a downward direction.
The book and the table both have acceleration (due to gravity) of 9.8 m/s/s.
The book’s weight and the upward force the table exerts on the book have equal magnitude but opposing directions.
The book’s weight and the upward force the table exerts on the book have equal magnitude but opposing directions.
The book resting on a table is in a state of equilibrium because the book's weight and the upward force the table exerts on the book have equal magnitude but opposing directions.
The book resting on a table is in a state of equilibrium because the upward force exerted by the table on the book is equal in magnitude and opposite in direction to the downward force of gravity acting on the book. This creates a balanced condition where the forces on the book are canceling each other out.
To understand why this is the case, it's important to consider the concept of forces and equilibrium. In this situation, there are two main forces at play: gravity and the normal force. Gravity is the force pulling the book downwards, and it is caused by the gravitational attraction between the book and the Earth. The normal force, on the other hand, is the upward force exerted by the table on the book, which counteracts the force of gravity.
In equilibrium, the sum of all forces acting on an object is equal to zero. So in this case, the force of gravity is counteracted by the normal force, resulting in a balanced condition where the book remains at rest on the table. This equilibrium is possible because the weight of the book (due to gravity) and the upward force exerted by the table have equal magnitudes but opposite directions.
So, to answer the question, the book is in a state of equilibrium because the forces acting on it are balanced; the weight of the book and the upward force exerted by the table have equal magnitudes but opposite directions.
