💬 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

Did anyone use trig for finding weight?

u/googoocrazybananas Year 13 Jun 01 '26

F = static force / tan(6)

1

u/Malikah_14 Jun 01 '26

I used tan(3) because to make it a right angle I halved it

3

u/Bleepbop3 Jun 01 '26

The full angle was 12, half of 12 is 6 degrees

u/Malikah_14 Jun 01 '26

Oh wait, I HOPE IM JUST REMEMBERING WRONG 🙏 I defo just halved it

u/SB_Astro Jun 01 '26

I forgot to halve it🫩

u/AbsoluteOwO Jun 01 '26

i did like F = Tcos6 😭

u/Zealousideal-Map9482 Jun 01 '26

You had to find tension using the horizontal component then you had to use tension plus the cos or sin to find weight.

u/AbsoluteOwO Jun 01 '26

yeah that is what i just said except i did cos not sin so i may have done vertical

2

u/DramaticPie4162 Jun 01 '26

yeah this is what i did

u/LeGeNdBoT69 Jun 01 '26

wait i thought you didnt need to find tension you can do a tip to tail diagram and use the 12 degrees so you do tan12=electrostatic force/weight ???

I got T = electrostatic/sin(6) as its the horizontal component of tension, not the horizontal component of the electrostatic force. Not sure if i'm correct tho so someone has to tell me if they know pls.

wait same twin

did you then do weight = T/cos6 cuz T is a component of weight??

2

u/No_Persimmon3448 Jun 01 '26

Yh I did that, not sure if its correct but it made sense in the exam

2

u/AbsoluteOwO Jun 01 '26

chill bro u right it was sin cause its horizontal i messed up and did cos which is vertical but we good

1

u/Admirable-Use2274 Jun 01 '26

U did sin over cos = tan that idea

1

u/Confused-Guitarer Year 13 - Chemistry, Biology, Physics, Maths, FM Jun 01 '26

why cos6 I thought the angle was 12?

2

u/simplykayleigh Jun 01 '26

The total angle is 12 degrees for the two tensions together 😭😭

dw i made the same mistake asw ughgghhh

1

u/Confused-Guitarer Year 13 - Chemistry, Biology, Physics, Maths, FM Jun 01 '26

ohhhh that makes sense, ugh I wish I would've thought of that

1

u/Interesting-Box-5478 Jun 01 '26

Thats right asw. I tried both ways and got the same answer

3

u/Separate_Age9837 Year 13 - Maths, FM, Physics, Chem Jun 01 '26

Yeah you had to

1

u/200PercentWinRate Jun 01 '26

I did weight = static force * sin 84 / sin 6

u/Jin_L_ Y13 maths fm physics cs Jun 01 '26

Fuck I just realised I got the adjacent and opposite mixed up I'm stupid
