    I'm hoping this is a mark scheme error:
    For part (b) I get:
     l = \frac{3}{2k}

    But the markscheme gets  l=\frac{2}{3} k

    In the past, whenever I blame the text for being wrong, It turns out I'm wrong

    Thank you for any help

    Edit: just to be clear, I did what the mark scheme did up untill that last line. (the markscheme gives two equations, then puts them together to find  l

    If you want the question (but I thought the mark scheme would be enough) here it is Name:  Untitled1.gif

    Mark scheme says \frac{3}{2}k which is clearly a transcription error, and as you and others have pointed out, it should be \frac{3}{2k}
