21.9GeV
i dont know how but :|
Total energy of the particles
initially are (10+10)= 20 GeV
Now we need to find the binding energy of the particles.
E =
^mc
2^m :
Mass defect The mass defect will be [940MeV/c
2 - - 940MeV/c
2] = 1880MeV/c
2 since both protons and anti-protons have same mass but are oppositely charged.
Therefore binding energy will be : E = 1880MeV/c
2 x c
2 =
1880MeVSo total energy available for products : 20GeV + 1880MeV =
21.9GeV
