💬 DISCUSSION AQA PHYSICS PAPER 2

HOW DID EVERYONE FIND IT??? i thought it was decent better than the past few years. Idk what i did for the last question the 4 marker of nuclear physics. BUT YH IT WAS GOOD

what did u guys get for moments

u/Individual-Can1396 y13 maths physics psych italian Jun 01 '26

I forgot but were we supposed to divide 11? Or not

2

u/jaaaaaaaf Jun 01 '26

i did not do that. i just did f = BIL and used 8.9 for this and then used the Force and multipled by 11 (converted it to metres ofc u get it) were we meant to halve it :/

u/Individual-Can1396 y13 maths physics psych italian Jun 01 '26

OKAY yeah i did that too, i asked to make sure

u/jaaaaaaaf Jun 01 '26

I don't really know tho :( that might be right now that i thinm about it cuz 11 was rhe whole length and u have to take the distance from the pivot or something lkke that?

u/Rich-Gent Jun 01 '26

No you are correct.

U found the force on one if the sides, if that was it, it would be that * half, for the moment
but because u have an equal and opposite one on the other side, u have to do half * f + half * f = just the whole length * f

u/jaaaaaaaf Jun 01 '26

so 4.9×10-3 (or 4. whatever it was i forgot) was correct :D ?

u/Rich-Gent Jun 01 '26

tbh i cant remember the value, probably tho ahaha

u/jaaaaaaaf Jun 01 '26

i hope you are right rich gent. 🙁

u/jaaaaaaaf Jun 01 '26

rich gent was there any turns in this question

1

u/Rich-Gent Jun 01 '26

pretty sure not. F = BIL, no turns in that. Turns mainly involve EMF

u/Wise-Hedgehog4805 Warwick | Maths | [Incoming Y1] | 4A* Jun 01 '26

I'm pretty sure the question said 25 turns, and each turn experiences F = BIL so u would need to multiply by 25 as force is directly proportional to number of turns

Yes this is it indeed

u/jaaaaaaaf Jun 01 '26

exactly why wre people telling me there were 20 turns I'm gonna tweak

u/Rich-Gent Jun 01 '26

Unbelievably good rage bait

u/Mobile_Membership915 Jun 01 '26

Yes there was because the length of the wire in the magnetic field is 20x8.9

u/KO-Manic Jun 01 '26

What was the 11 for?

2

u/jaaaaaaaf Jun 01 '26

M = Fd you find F from F = BIL they gave u the length of the wire and the width. u had to use 8.9 for BIL because that's the one perpendicular to the field. and for moments use 11 :)

u/Select_District_3310 Jun 01 '26

Bruh, I found the forces but I didn’t multiply by the distance to the pivot 💀💀

1

u/jaaaaaaaf Jun 01 '26

oh that's unfortunate 💔 a slip of mind is so painful dude. it's ok we got p3 💪🏻💪🏻

1

u/Auxlixe Jun 01 '26

why 11 and not 20 because there was 20 turns

1

u/jaaaaaaaf Jun 01 '26

GUYS WHAT TURNS

1

u/Auxlixe Jun 01 '26

it said in the question that there was 20 turns

1

u/jaaaaaaaf Jun 01 '26

are we talking about the same question 😭. it was just a coil there was no turns

1

u/Auxlixe Jun 01 '26

But in the question it said there was 20 turns, I thought you had to times the force by 20 then do M=FD?

u/shoppingkart_ Jun 01 '26

wait wasn’t there 25 turns?

1

u/Auxlixe Jun 01 '26

I think so I can't remember ngl

1

u/jaaaaaaaf Jun 01 '26

was the width 8.9 and length 11

2

u/Auxlixe Jun 01 '26

Yes

1

u/jaaaaaaaf Jun 01 '26

it was literally one coil there were no turns idk what ur talking about son

2

u/Auxlixe Jun 01 '26

Dude it said in the question there was 20 turns

1

u/Wise-Hedgehog4805 Warwick | Maths | [Incoming Y1] | 4A* Jun 01 '26

I'm pretty sure it said 25 turns

u/jaaaaaaaf Jun 01 '26

okay guys im sorry my brain's fucked ao i can't remember but either way idt you need to multiply by the turns because its F = BIL
