QNEET-2013-Ph-1513: NEET 2013 Physics - Class 12 NEET-2013-Ph-1513 Solution: A certain mass of Hydrogen is changed to Helium by the process…
A certain mass of Hydrogen is changed to Helium by the process of fusion. The mass defect in fusion reaction is 0.02866 u. The energy liberated per u is (given 1 u = 931 MeV) 6.675 MeV 13.35 MeV 2.67 MeV 26.7 MeV
Multiple Choice Options
- A 6.675 MeV
- B 13.35 MeV
- C 2.67 MeV
- D 26.7 MeV
Step-by-Step Verified Solution
Mass defect _ m = 0.02866 a.m.u.
Energy = 0.02866 _ 931 = 26.7 MeV
As 1 H 2 + 1 H 2 _ 2 He 4
Energy liberated per a.m.u = 13.35 2 MeV
= 6.675 MeV
