How did everyone find A Level Eduqas physics paper 2?

How was paper 2 guys? Personally I found it a little harder than paper 1, but that might just be because I did less revision for this one.

Also what did you say for the question with the article about dark matter that asked how the scientific community should proceed? I had no idea what they were looking for with that

For the scientific community one, basically any of these would work :
peer review (other scientist try the same experiment)
Redoing it using different telescopes around the globe / use telescopes in outer space (telescopes on earth only see IR radiation, other wavelengths absorbed by atmosphere)
trying the theory again and making sure it’s 100% correct / not flawed theory.

Found rest alright but the question with the two plates and the ball, I honestly didn’t have a clue and just blanked. Looking back, it seems straight forward so lost 4 marks there..

Paper was a solid 7.5/10
Messed up the uncertainty for the area on resistivity question because I multiplied it by 2 but apparently you weren't meant to.
Pendulum question for the horizontal component of force I did mgcosx when you were meant to do Tsinx instead.
For the find the initial charge on capacitor you were meant to count the squares under but I didn't do that. Also got some other explain questions probably lacking but yeah that's a few of mine.

wait for the uncertainty question did they give the area already? Or did they just give the diameter / radius? I also messed up the initial charge of the capacitor - I just did the initial current divided by 0.02 for no reason haha. Didn’t get the question with the charged ball at all. Rest was fine.

Yeah in the uncertainty question, the area was already given so you didn't need to multiply the absolute uncertainty of the area by 2. Quoted from my friends

aha got me worried there. what was the method for the ball question?
