would you say that "the two forces exerted on the book ar ethe normal force directed up and the weight of the book directed down. These are equal and opposite to one another. By newton's third law they are a third law force pair, so the normal force is always equal to the weight of the book."
The Attempt at a Solution
I said disagree, since the normal force is exerted by the table, not the book, and the rest of the concept seems right.
