    Higher than last year. Last year was probably about as low as they could go and this paper seemed more straightforward.

    For the multiple choice with 2nc and -1nc you added 2nc to both didnt you? So it would repel by 4F? I wasn't so confident
    As r is constant, F is proportional to the charges multiplied together!

    First scenario: F = 2q x -q = -2q^2
    Second scenario: F = 4q x q = 4q^2

    So I said the magnitude was 2F!

    Definitely higher, last year was arguably the hardest ever paper, this year was more or less straightforward for the most part

    For the 2 EM laws, did you just write faradays and lenzs law?
    Yes, in words
    (Original post by BioStudentx)
    No... you had to explain. Doubt you'd get more than a mark just stating...
    They don't mean just writing "faradays law", they mean stating it in words

    Also guys what's an A* likely to be?? 61-63?

    A bit higher I think between +2 to +4 for some grades

    What did everyone get for the momentum calculation?(didn't bother with that disgusting proof!) i got 1.14x10-13 which i'm sure is wrong-.-

    Less than that for an A* probably. 58-60?

    what did people get for the one with the right angled triangle in a gravitational orbit?
    3F, using pythagorus you can work out the distance between them was (root 3)R in the triangle and then just R when they are in line, F is inversely proportional to R squared so in the triangle the force was a third of the size!

    A quick tip for everyone. I retook unit1 and unit3 this year and also have just done the unit 4. Ive seen that in these papers they have simply taken questions from previous years and changed bits around. So for unit5, it will be same as previous papers.
    So try doing ALL past papers and make sure youll understand every question in there as this years unit5 will be very similar to previous years. Also so far AQA has been setting easy-ish papers, so if u think you messed up todays unit4, remember that unit 5 will be an easy paper which you can gain a lot of UMS on. Goodluck

    Cocked up the question after the 6 marker...said g will be 1/4 of actual value rather than x4

    Few MCQs tricky, cap & em induction part was straightforward and the momentum part was tough.

    Attachment 553448did everyones graph look like this????
    Does it matter if I'd drawn mine a little pointy rather than as curvy as yours?My 'pivot' point was just a little over the middle bit closer to Venus. Do you think I will get all three marks on that?

    yeah i got same. I think people missed the 'decrease BY 80% '
    I got that too since 12V decreased by 80%

    I got 3F

    Used pythagorus to find distance between them before was root3r

    When they are closest they are 1r apart

    So you divide r by root3 and square it due to proportionality to get 3F

    Hope thats right
