The reaction force is NOT > an equal and opposite force that acts on B. You are confusing reference frames. I repeat to you once more a fact you seem you do not want to accept: Newton's law apply without modification only in inertial reference frames. This holds for the second law and it must also hold for the third law. In the inertial frame, the reaction to the centripetal force is the centrifugal force. In a non-indertial reference frame, there is no issue of action-reaction since these two forces must cancel each other to have the state of rest. There is no net action in a non-inertial reference frame and this was the point all along. If you keep jumping around reference frames you will never get it straight. Mike |
