see a picture above. throwing a ball to the wall its will make a ball bounce back. a pairs of action or reaction force correct is...

• F1, F2, and F3 because that force draw a ball movement

• F1 and F2 because that work to the same objects and perpendicular in direction

• F1 and F3 because that work to the different objects and perpendicular in direction

• F2 and F3 because that work to the different objects and apposite in direction
