A 5.0 kg book is sitting on a table. Which describes the force acting on the book
a. there are no forces acting on the book
b. the force of the table upward is greater than the force of gravity downward
c. the net force on the book is zero

My answer is A
Doesn't gravity act on the book? Does the book float on the table?
