| A heavy nucleus \[x=(A=180)\] breaks into two nuclie \[y=(A=140)\] and 2(A=40). Energy released during fission reaction is - |
 |
A) 110 MeV
B) 220 MeV
C) 200 MeV
D) Energy is not released
Correct Answer: B
Solution :
| Released energy =\[=140\times 7+8\times 40-180\times 6\] |
| \[=980+320-1080\] |
| \[=\,\,220\,\,MeV.\] |
