To determine the direction the book will move, we can analyze the forces acting on it. The pushing force acting to the right is 7 N, while the frictional force acting to the left is 3 N.
To find the net force acting on the book, we subtract the frictional force from the pushing force:
Net force = Pushing force - Frictional force
Net force = 7 N (right) - 3 N (left)
Net force = 7 N - 3 N = 4 N (to the right)
Since the net force is 4 N to the right, the book will move to the right.
The answer is: The book will move to the right.
