Newton's Third Law of Motion says: Forces always come in pairs: when one object exerts a force on a second object, the second exerts an equal and opposite force on the first. If you pull horizontally on a door handle (action) this second force (reaction) is
A) the frictional force of the floor against the soles of your shoes.
B) the force that the door handle exerts on your hand.
C) directed vertically down.
D) the dark force.
E) the force that the door exerts on the hinges.
