    1. The problem statement, all variables and given/known data
    Two bodies P and Q having masses Mp and Mq respectively exert forces on each other and have no other forces acting on them. The force acting on P is F which gives P an acceleration a.Which of the following pairs is correct?

    Magnitude of force on Q Magnitude of acceleration of Q

    A. Mq/Mp*F a
    B. Mp/Mq*F a
    C. F a
    D. F Mp/Mq*a
    E. F Mq/Mp*a

    2. Relevant equations

    3. The attempt at a solution

    Magnitude of Force on Q: F because of newton's third law
    Magnitude of acceleration: a

    Can you explain your reasoning for choosing that answer? Otherwise, for all we know, you just guessed, which doesn't exactly qualify for attempting to solve the problem yourself.
