| Feb 23, 2014 at 8:45 | comment | added | John Rennie | @user22180: this also confused me when I first encountered it, and I'm still not sure I fully understand what's going on. The difference between a nucleus and a proton is that the quarks in a proton are confined and to separate them to infinity would take an infinite energy. Unlike a nucleus you cannot even theoretically start at large separation and consider what happens as you bring the quarks together. | |
| Feb 23, 2014 at 8:28 | comment | added | user22180 | Though my original question is resolved from the two answers. But I am not able to apply the same concept that you have told in the case of quarks forming a proton or neutron. m(u)=2.3 MeV , m(d)=4.8 MeV , then how come mass of protron is 931 MeV if you want to bring analogy with "nucleons forming nucleus"? | |
