Final answer:

When carrying a book across the room at a constant velocity with the force being perpendicular to the motion, no work is done.


Explanation:

No, the force applied is perpendicular to the direction of motion. When carrying a book across the room at a constant velocity, since the force is perpendicular to the motion, no work is done on the book. Work is only done when there is a component of the applied force in the direction of motion.
