Assume that a neutron break in a proton and an electron. The energy released during this process is: Mass of neutron =1.6725 xx 10^(-27)kg Mass of proton =1.6725 xx 10^(-27)kg Mass of electron =9 xx 10^(-31)kg

Answer»

5.4MeV
0.73MeV
7.10MeV
6.30MeV

Solution :`trianglem=m_(n)-m_(p)-m_(E)=- 9 XX 10^(-31)kg (m_(p) approx m_(n))`
`triangle E=trianglemc^(2)=9 xx 10^(-31) xx (3 xx 10^(8))^(2)`
=0.511MeV
Which is NEARLY equal to (b) 0.73MeV.
