First Image
answer :- Diagram B
The book is on the table so vertical force will balance each other ( weight of the book and normal force )
as the book is not moving so horizontal force will balance each other and will be of same magnitude and will be in opposite direction.
Second image ( same as third image )
answer :- Diagram B
The book is on the table so vertical force will balance each other ( weight of the book and normal force )
As the book is moving with constant speed that means there is no acceleration and that means there is no external force is acting on the book . So horizontal force will be of same magnitude and opposite direction.
feel free to drop comment if you have any doubt.
