Solution:
As we know;
A)
Given rest energy of the parent particle, E = 8.94 GeV
                                                        Â
= 8.94 x10 9 eV
= 8.94 x10 9 x1.6 x10 -19 J
As, E = mc 2
=> Rest mass of the parent particle, m = E / c
2
=> m = (8.94 x10 9 x1.6 x10 -19 )/( 3
x10 8 ) 2
                                        Â
= 1.589 x10 -26 kg
B)
Energy released = 8.94 - (6.72 + 1.3) Gev = 0.92 Gev = 920
MeV
