Mg: force acting by the book on the table

F:Force applied to the book

f: friction force ... acting opposite direction of motion of book.

Answer 2

Answer:

We can understand that the floor applies a force on the book against its motion. Similarly the book also applies the same amount of force on the floor in the opposite direction. Here it is clear that the floor is at rest. Hence the net force acts in the direction of the force applied by the floor on the book.
