The nuclear reaction ₁ H ^1+ ₁ H ^1 ₂ He ^4 (mass of deuteron =2.0141 amu and of He =4.0024 amu ) is

Options

Afusion reaction releasing 24 MeV energy
Bfusion reaction absorbing 24 MeV energy
Cfission reaction releasing 0.0258 MeV energy
Dfission reaction absorbing 0.0258 MeV energy

Correct answer

A. fusion reaction releasing 24 MeV energy

Step-by-step solution

₁ H ^1+ ₁ H ^1 ₂ He ^4 Mass defect aligned m & =2 mass of 1₁ H ^1- mass of ₂ He ^4 & =2 2.0141-4.0024 & =0.0258 aligned aligned Energy released & = m 931 MeV & =0.0258 931=24 MeV aligned
