Answer:
NO
Step-by-step explanation:
As we know by work energy theorem that work done by all forces is given by change in kinetic energy of the system
it is given as

so here since the kinetic energy is constant for the system
so here change in kinetic energy is zero
hence the net work done must be zero
Here we know that

so here we can say that

so no work is required to move the books at constant speed from one position to other position
