AQA Physics PHYA4 - Thursday 11th June 2015 [Exam Discussion Thread]

You actually use W=Fs (Work done in joules = Force x distance).
You do 4x10-16J/63mm to work out force. Do not fall into the trap of trying to derive an equation Q or r, as this only works if there is more than one charge.
Also the charge moves, and you are provided with distance and work done (which = kinetic energy)

Hope this helps

Will post a multiple choice mark scheme today and one for part B (whenever I can get a pdf/other online copy) (mine is paper only)

As usual CD223, I can't even give you enough reps for this resource.

This question comes from Q2aii of the June 2014 paper in which you have to use the equation Ep=QE delta d. This equation is obviously not on the equation sheet (I didn't actually know this equation). Do either of you have a list of all the equations that we need to know that aren't on the equation sheet?
Or do you have any tips on deriving these equations from equations that we are given?

If thats the case, are you willing to post it here once you have it? )))))

Just made the 1000th post!

Has anyone got any ideas on how to prepare for the 6 mark questions? I never seem to get my points across clearly enough and it loses me marks. I'm not sure how I can prepare for them because there are so many possibilities for questions but there are only a few past papers! (this is applies to unit 4 and 5)

What do you guys do to prepare for the dreaded 6 mark questions?

I'm gonna make revision cards for every past paper 6 marker so I can remember the points that come up

That seems like a good idea - thanks I'll probably try that.

Do you ever find that some of the points made on the mark scheme for the six markers are a little bit... irrelevant? Some of them seem a little bit mad and unrelated to me. Oh well I can't moan because I've still got to sit the exam so I'll just have to learn it :L

QUOTE=CD223;55118009]Oh brilliant! I've got my "corrected" paper but it's only a paper copy and lacks a mark scheme :/

Here it is: AQA-PHYA4-W-MS-Jun14.pdf

Thank you! When I get the digital copy I'll post the question paper

Oh wow brilliant thank you! I've got the 2014 phya5 paper as a mock in the next two weeks :/

Have fun

We did 2014 for our mock and it isn't a bad paper really? Can't compare it to others because I haven't managed to do any yet but it didn't feel particularly hard.

Dw the grade boundaries are really low!
Honestly my plan for the real one is to do try to do really well in my option unit medical since its like 18/40 to get an a so that way i can bag a few extra marks! I'm finiding thermal and nuclear quite hard i mean the content is alright but the questions a pretty hard! But i guess after the few past papers that there are i should be better! Thanks for your notes they're amazing 😊

Just got mine, I'll post it now!

I can upload it today if you want (and the mark scheme)
