A book is resting motionless on a table. Even though the book is not moving, there are forces acting on it. Which of the following correctly describes how these forces would change if someone were to slide the
book to the opposite side of the table?
A. The normal upward force and the downward force of gravity would become unbalanced.
The applied contact force would become higher than the opposing force of friction.
0. The force of friction would be greater than the opposing pushing force.
D. The downward force of gravity would be less than the applied force.
B.

A. The normal upward force and the downward force of gravity would become unbalanced.

Explanation:

(Thus the book moves. The friction is implied, as the book only moves to the other side of the table and doesnt go on sailing through the room and into the neighboring building.)
