Neet Solved Paper 2013 Question 36
Question: 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)
Options:
A) 2.67 MeV
B) 26.7 MeV
C) 6.675 MeV
D) 13.35 MeV
Show Answer
Answer:
Correct Answer: C
Solution:
- Here, $ \Delta m=0.02866,U $
$ \therefore $ Energy liberated $ =\frac{0.02866\times 931}{4}=\frac{26.7}{4}MeV=6.675MeV $
