A book is sitting on a table, completely still. What would happen if gravity suddenly stopped affecting the book? The book would move upward. The book would stay where it is. The book would move sideways. The book would fall.
Gravity is a force that pulls objects down. If there was no gravity the book would not fall, nor would it move unless it is acted upon by an outside force.
So your answer would be, The book would stay where it is
