Question

If a proton is completely converted into the energy, then the energy produced will be :

• A. 0.51 MeV
• B. 1.02 MeV
• C. 185 MeV
• D. 932 MeV

Answer 1

Answer: (D)

932 MeV

Energy released if proton is completely converted into energy $=m_p{c}^2=1.672\times {10}^{-27}\times (3\times {10}^8{)}^{2}J=\frac{1.672\times {10}^{-27}\times (3\times {10}^8{)}^2}{1.6\times {10}^{-19}}eV\approx 932MeV$
