A book rests on a table.  The force of gravity pulls down on the book with a force of 20 newtons. What prevents the books from accelerating downward at 9.8 m/sec²    

• The table presses back up on the book with an equal and opposite force of 20 newtons.
• The table presses back up on the book with a force greater than 20 newtons.
• The table and the book together are accelerating downwards at  9.8 m/sec²
• The inertia of the book holds it up
