  • A
    No force acts on it

  • C
    Force exerted by book on the table, is same as the force exerted by the table on the book
  • D
    All of the above

Answer

  1. Force exerted by book on the table, is same as the force exerted by the table on the book

Explanation:

According to Newton's third law, the table exerts the same force on the book as the force that the book applies on the table.

Thus net force acting on the book is zero and hence the book remains at rest on the table.
