Question

If a book is sitting on a table and not moving, what is the net force acting on the book? Options: A. Zero B. 10 N down C. 10 N up D. 100 N

Answer 1

The book on the table is not moving because the forces acting on it, namely gravity pulling it down and the table pushing it up, are balanced. This results in a net force of zero.

Step-by-step explanation:

In the given scenario, the book is described as sitting still on a table. This indicates that the forces acting upon the book are balanced. There are two forces at work here. The first is gravity, which pulls the book downward, and the second is the table's support force, which pushes up against the book. According to Newton's first law of motion, an object at rest tends to stay at rest unless acted upon by an unbalanced force. In this case, the two forces cancel each other out, resulting in a net force of zero. So, the correct answer is A. Zero.
