Question

The sun is believed to be getting its energy from the fusion
of four protons to form a helium nucleus and a pair of
positrons. Calculate the release of energy per fusion in
MeV. Mass of a proton = 1.007825 a.m.u.; mass of
positron = 0.000549 a.m.u.; mass of helium nucleus =
4.002603 a.m.u.; 1 a.m.u. is equivalent to 931 MeV.
[Ans. 25.695 MeV]​

Answer 1

Answer:

men .mass of a proton =1.007825a.m.u.;

mass of positron =0.000549a.m.u.;mass of helium nucleus=

4.002603a.m.u.;1 a.m.u. is equivalent to 931 Mev.

answer=25.695Mev
