Regarding action reaction forces

  1. Mar 2, 2012 #1
    When I apply a force to a wall and the force applies a contrary force, what is causing the wall to apply this force on my hand on the atomic scale?

    The electromagnetic force repels the atoms in your hand away from the atoms in the wall.
