1) There is a net force acting downward on the  book

2) The weight of the  book equals the weight of the table

3) The acceleration  due to gravity  is 9.8  m/s^2 for both the book and the table

4) The weight of the book and the table's upward force  on the book are equal in magnitude , but opposite in direction
