Edexcel P3 Physics - 23rd June 2014

Aside from being the last exam and the euphoria that will be flowing because of that, how did everybody find it?

It was definitely the hardest out of the three extension exams in my opinion.

Do you think the first six mark question wanted you to actually state the charges that occur using equations?

I said:

Beta + occurs when there are too many protons
Positron is released
Up quark into down quark
Charge of 0

Beta - when there are too many neutrons
Electron is relased
Down quark into up quark
proton made


is that wrong?

Both inelastic collision thus momentum is conserved and kinetic energy is displaced?:biggrin:

That's basically what I wrote, and considering how little space was given I think that's all you were really supposed to include.
