• # question_answer When the mass equal to one a.m.u. is converted completely into energy, then the energy produced is A) $1.5\times {{10}^{-18}}Joule$  B) $1.5\times {{10}^{-14}}Joule$ C) $1.5\times {{10}^{-12}}Joule$  D) $1.5\times {{10}^{-10}}Joule$

$E=\Delta m{{c}^{2}}$     $=931.5MeV$     $=931.5\times {{10}^{5}}\times 1.6\times {{10}^{-19}}J$     $=1.5\times {{10}^{-10}}J$
