Atoms And Nuclei Question 262
Question: In the reaction $ _{1}^{2}H+ _{1}^{3}H\to _{2}^{4}He+ _{0}^{1}n $ . If the tending energies of $ _{1}^{2}H _{1}^{3}H\text{ and } _{2}^{4}He $ are respectively $ a,\text{ b and }c $ (in MeV), then the energy (in MeV) released in this reaction is [CBSE PMT 2005]
Options:
A) $ c+a-b $
B) $ c-a-b $
C) $ a+b+c $
D) $ a+b-c $
Show Answer
Answer:
Correct Answer: B
Solution:
During fusion binding energy of daughter nucleus is always greater than the total energy of the parent nuclei so energy released = c - (a + b) = c - a - b
