To determine the direction the book will move, we need to analyze the net force acting on it.

  • The pushing force applied to the right is 7 N.
  • The frictional force acting to the left is 3 N.

To find the net force, we subtract the frictional force from the pushing force:

Net force = Pushing force - Frictional force Net force = 7 N (right) - 3 N (left) = 4 N (right)

Since the net force is 4 N to the right, the book will move to the right.

So, the correct response is:

The book will move to the right.
