A) \[0.38\text{ }MeV\]
B) \[0.70\text{ }MeV\]
C) \[1.40\text{ }MeV\]
D) None
Correct Answer: C
Solution :
Conservation of Energy, \[Photon\to {{e}^{+}}+{{e}^{-}}+energy\] \[{{E}_{P}}={{E}_{r{{e}^{+}}}}+{{E}_{r{{e}^{-}}}}+K.E.\] of both \[{{e}^{-}}+{{e}^{+}}\] We know that rest mass energy of \[{{e}^{+}}+{{e}^{-}}\]is.\[5\text{ }MeV\] Hence \[{{E}_{p}}=.5+.5+.19\times 2=1.40\,MeV\]You need to login to perform this action.
