I remember Paul D answering this question by comparing
the total number of neutrons protons and electrons for
the two objects in question. Forgive me butchering his
explanation, but since a piece of paper is made of
fewer atoms than is a book, the force of gravity
exerted by it and therefore on it (Law 3) is less than
for a book. Now, the question how does the Earth know
that the paper is made of fewer atoms than is the book
is a much deeper question. I think I am paraphrasing
Feynman when I say...nobody knows.
