Assume that a neutron breaks into a proton and an electron . The energy reased 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 )`

A

`5.4 MeV`

B

`0.73 MeV`

C

`7.10 MeV`

D

`6.30 MeV`

Text Solution

Verified by Experts

The correct Answer is:
B
Released energy
`=(1.6747xx10^(-27)-1.6725xx10^(-27)-9xx10^(-31))xx (3xx10^(8))^(2)J=0.73 MeV`
