    it was a weak exchange particle because strangeness was not conserved (or because of the change in type/flavour of quarks.
    it had to be W- because it transferred negative charge. the s quark had to had a charge of -1/3 because it was with 2 other u quarks (charge +2/3) in a one positive baryon.the product of that decay were a u bar (Q=-2/3) and a d quark (Q=-1/3).
    did the paper ask for the binding energy PER NUCLEON or just the binding energy. i have a feeling that it was the binding energy per nucleon, but i must have been careless in reading the question and calculated the binding energy.

    i only knew 1 [strong nuclear force] range 10^-14m, does not effect electrons. Then i said weak nuclear force for next 1 and made the range up, im thinking i should of put electromagnetic. I thought this paper was average [not easy not hard in terms of particle physics], not hard to get 100% though.

    i know... its was OK... i did some DUMB mistakes.. still.. the paper went well... usually.. i think particle papers r more easier... hmmmmmmmm.. lets c... do u know the A mark for usuall papers. i think its some where around 24 or 25..
    ............ hmm.. im still so depressed .. could have done a lot better..
