D
Actually, the situation is a bit more complicated than that. On a frictionless surface, the books would in fact move slightly, as the paper would pull slightly on the books. The real reason the books do not move at all is because of the static friction between the books and the shelf.
A paper placed in between two books can be quickly pulled out without moving the books. Which statement explains this phenomenon?
A.
There are no forces acting between the books and the paper.
B.
The pull of gravity on the book is greater than the force of gravity on the paper.
C.
The two books exert force only on each other and not on the paper.
D.
The books have a great deal of inertia and do not move easily.
