46.What is the energy equivalence of one atomic mass unit? [A] 93.125 eV [B] 931.25 eV [C] 9.31 eV [D] 0.93125 eV Show Answer
Solution : 1 amu = `1.66xx10^(-27)kg=m,c=3xx10^(8)ms^(-1)` <br> 1 eV = `1.6xx10^(-19)J` <br> E = `mc^(2)=1.66xx10^(27)xx(3xx10^(8))^(2)=14.94xx10^(11)J` <br> = `(14.94xx10^(-11))/(1.6xx10^(-19))933.7xx10^(6)eV=933MeV`.
