    For everyone debating question 5 whether it was a push or a pull, the question said "above the horizontal".

    This is what above the horizontal means
    Attachment 424229

    And this is what below the horizontal is ie a pushing force in the case of this question

    Attachment 424233

    Therefore (I believe) it can only be a pulling force due to the phrasing of the question.
    It seems lots of people have made the same mistake however, so OCR might decide to put some MR marks on the markscheme, so you could still get half or more of the marks if you otherwise were correct in your working. Perhaps not though.

    My teacher said they haven't specified so they are writing to the exam board to let them know. However he may have missed the "above the horizontal" phrase too

    However there is nothing on the specification about this, I checked today, therefore I think they'd have to give full marks for both, you can't phrase a question based on terminology that's nowhere on the spec surely
