Show that 1 amu = 932 MeV....

Show that 1 amu = `932 MeV`.

Text Solution

Verified by Experts

From Einstein's relation `E=mc^(2)`
`m=1 amu=1.661xx10^(-27)kg and c=2.998 10^(8)ms^(-1)`
`E=1.661xx10^(-27)xx(2.998xx10^(8))^(2)=14.929xx10^(-11)J`
`=(14.929xx10^(-11))/(1.602xx10^(-19))ev=9.318xx10^(8) MeV=931.8 MeV`
`therefore` Energy equivalent of `1 amu=932 MeV`.
