Anyone get the percentage uncertainty on the specimen paper for component 3? All we keep getting is 0.4x10^-34 as the absolute? There are already many errors in the mark scheme for this question so would just like a general consensus

first of all im confused because it's asking for percentage uncertainty yet the mark scheme is an absolute uncertainty. the percentage uncertainty in each gradient summed which is equal to +/- 15.57% which is +/- 0.8x10^-34 although i didn't get the exact values for the gradient so mine was slightly different. But the % uncertainty is defo 15.57%

This paper is gonna be ****ing hard

That went quite well, got the wrong moment of inertia though, didn't even realise we needed to know them haha

How did everyone else find it? I thought it wasn't too bad, just short on time tbh

Was really worried about magnetic induction stuff, but seemed pretty fair when it came up. Also there seemed to be quite a few derivation questions that I didn't know we had to know

I messed up the radioactivity part with the ratios and the higgs boson lost like 9 marks
