Question

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?

Answer 1

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

Answer 2

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.

Answer 3

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