A 25 N book sits on a table. What is the magnitude of the normal force the table exerts on the book?

  • Physics -

    Hint: The acceleration of the book is zero. Therefore, the sum of all the forces that act on the book is zero.

  • Physics -

    Newton's 3 law:
    For every action there is an equal and opposite reaction: ↑ N == mg↓
    normal force N = mg = 25 N
