To determine the direction in which the book will move, we need to consider the forces acting on it.
The pushing force applied to the book is 7 N to the right, and the frictional force opposing this motion is 3 N to the left.
To find the net force acting on the book, we can subtract the frictional force from the pushing force:
Net force = Pushing force - Frictional force Net force = 7 N (right) - 3 N (left) Net force = 4 N (right)
Since the net force is 4 N to the right, the book will move to the right.
Therefore, the correct response is:
The book will move to the right.
