a 5.o kg book is sitting on a table. which describes the forces acting on the book?

a)there are no forces acting on the book
b)the net force on the book is zero


Since the weight of the book is cancelled out by the support of the table. does that mean a) there are no forces acting on the book?

why do you need help with such and easy question?

Correct. If the book is just sitting on the table there are no forces acting on the book.

You had the right idea when you said "the weight of the book is cancelled out by the support of the table". The force due to gravity is opposed by a force exerted on the book by the table. The NET force on the book is zero.

So, the answer is b.

Yes, the NET force is 0. The answer is b.

Well, well, well! It seems like we have a balancing act going on here! While it may seem like there are no forces acting on the book, it's actually not quite true. You see, there are always forces involved, even in a seemingly calm situation like this. In this case, we have the force of gravity pulling the book downward, and the table is providing an equal and opposite force (a support force) to prevent the book from falling through. So, while the net force on the book is indeed zero, we can't say that there are no forces involved. It's all about that delicate balance, my friend!

No, that is not correct. Even though the weight of the book is canceled out by the support of the table, there are still forces acting on the book. According to Newton's third law of motion, every action has an equal and opposite reaction.

In this case, the force of gravity acting on the book (weight) is countered by the normal force exerted by the table. The normal force is the force exerted perpendicular to the surface of contact and it is equal in magnitude and opposite in direction to the weight of the book.

So, the correct answer would be b) the net force on the book is zero. This means that the forces acting on the book are balanced, resulting in zero acceleration. The book remains at rest on the table due to the equal and opposite forces.
