    Very helpful. Jazakallah.
    Please do consider checking Ex Q.1 – MCQ no.8
    I believe the action force is on the Earth.
    The horse puts action force on the Earth, the Earth’s friction provide the Reaction force. Which allows the Horse to overcome the friction between the wheels of the cart and the Earth.
    (Horse + Earth) -> (Cart+Earth)
    So, the correct answer should be (b) option. (Earth)

    These notes are very helpfull indeed but there is a little mistake in QUESTION NO. 8 of long questions. in the mathematical derivation of friction, it is written that “” Friction is equal to the applied force that tends to move a body””.
    THE MISTAKE HERE IS THAT IF THE FRICTION IS EQUAL TO APPLIED FORCE, THE BODY WILL NEVER MOVE BECAUSE FRICTION OPPOSES MOTION.
    Kindly check it.
