Final answer:
The support force or normal force exerted by the table on a book weighing 35 N is also 35 N, as it balances the weight of the book to keep it at rest.
Step-by-step explanation:
When a book with a weight of 35 N is placed on a table and remains at rest, the support force, or normal force, that the table exerts on the book is equal to the weight of the book. This is in accordance with the concept of equilibrium where the net force on the book is zero when it is at rest. Since the book is on a non-accelerating horizontal surface, we can say that the normal force (N) the table exerts upward on the book equals the downward weight (mg) of the book, which is 35 N.
