... This is not the only correct choice. This is true according to Newton’s third law. Since block 1 exerts a force (action) on block 2 by being pushed into it, block two must exert a force (reaction) on block 1. This pair of forces, as with all action-reaction pairs, act in opposite directions, and hav ...
