Hey- could someone please help me with the free body diagrams. If there is a hand pushing on a book,laying on a table- what are the forces acting on the book? I thought they were normal force, force of hand and gravity.

Consider the presence of a friction force as well. It will be directed opposite the force of the hand. Otherwise, the three you named is it.
Will there be friction, if the hand is acting upon the book from above?
