. Two deuterons undergo nuclear fusion to form a Helium nucleus. The energy released in this process is

Best Answer

Ans: C

Sol: Nuclear fusion is a phenomenon in which two or more atomic nuclei are combined to form one or more different atomic nuclei. 

Given that two deuterons undergo nuclear fusion to form a Helium nucleus.
 

₁H² + ₁H^2----₂He⁴ 

Initially, the binding energy of deuterons is 1.1 × 4 = 4.4 MeV

Final energy after fusion is, the energy of helium = 4 × 7 = 28 MeV

released energy=  28 – 4.4 = 23.6 MeV
