The radio nuclide $_6C^{11}$ decays according to $_6C^{11} \to _5B^{11}+e^++\gamma$ half life $=20.3\;min$ The maximum energy of the emitted position is $0.960\;Mev$ given the mass values $m(_6C^{11})=11.011434 \;u\;m (_6B^{11})=11.009305$ calculate Q and compare it with maximum energy of position emitted .
