  • Newton's first law states that when viewed in an inertial reference frame, an object either remains at rest or continues to move at a constant velocity, unless acted upon by an external force.
Answer: there is no net force on the book
There are forces acting on the book, but the only forces acting are in the y-direction. .
Gravity acts downward, but the table exerts an upward force that is equally strong, so the two forces cancel.
Therefore, the net force is zero.
