    Do you know the answer to (i)? If so, try drawing a free body diagram for situation (i), and one for situation (ii), you'll notice something about the net force and torque in each case.

    Maybe you should read up on it a little. The hints they give you are pretty helpful.

    Think about calculating torque around a point that will yield a simple equation and then use a couple of those equations to get an expression for Q.
