(a)
The effect of weight of the book when reduce the applying force to the book in the same spot on the wall.
Answer to Problem 5QAP
The weight of the book is not changed.
Explanation of Solution
Introduction:
The book is pressed against on the wall. When we reduce the applying force to the book, the book remains in the same spot on the wall.
So the magnitude remains constant. Therefore weight stays the same.
Conclusion:
The weight stays the same.
(b)
The effect of the normal force of the wall on the book when reduce the applying force to the book in the same spot on the wall.
Answer to Problem 5QAP
The normal force of the wall on the book decreases.
Explanation of Solution
Introduction:
The book is pressed against on the wall. When we reduce the applying force to the book, the book remains in the same spot on the wall.
When applied force is reduced the normal force decreases.
Conclusion:
The normal force of the wall on the book decreases.
(c)
The effect of the frictional force of the wall on the book when reduce the applying force to the book in the same spot on the wall.
Answer to Problem 5QAP
The frictional force of the wall on the book is not changed.
Explanation of Solution
Introduction:
The book is pressed against on the wall. When we reduce the applying force to the book, the book remains in the same spot on the wall.
So the weight of the book is constant. Therefore the frictional force of the wall on the book stays same.
Conclusion:
The frictional force of the wall on the book stays same.
(d)
The effect of the maximum static frictional force of the wall on the book when reduce the applying force to the book in the same spot on the wall.
Answer to Problem 5QAP
The maximum static frictional force of the wall on the book deceases.
Explanation of Solution
Introduction:
The book is pressed against on the wall. When we reduce the applying force to the book, the book remains in the same spot on the wall.
When F reduces R decreases. Since
Conclusion:
The maximum static frictional force of the wall on the book deceases.
