The book will move to the left.
The book will move to the left.
The book will stay stationary.
The book will move to the right.
The book will move to the right.
To determine the direction in which the book will move, we can apply Newton's First Law of Motion. According to Newton's First Law, an object will remain at rest or continue to move at a constant velocity unless acted upon by an external force.
In this case, a pushing force of 7 N is being applied to the right, while a frictional force of 3 N is applied in the opposite direction. Since the pushing force is greater than the frictional force, there is a net force of 7 N - 3 N = 4 N to the right.
Therefore, the book will move in the direction of the net force, which is to the right.
So, the correct response is:
The book will move to the right.
