Question

The sources of energy obtained in a nuclear reaction are :

• A. Mass defect
• B. Binding energy
• C. Fission
• D. Fusion
• E. All of these

Answer 1

The correct option is E All of these

In fusion a heavy nucleus is splitted into two nuclei of comparable masses. The mass of parent nucleus is greater than the total mass of daughter nuclei, some mass is disappeared, this is mass defect and this mass appeared as the binding energy.

In fusion two or more than two light nuclei fuse together to form a heavy nucleus. The sum of masses of light nuclei is greater than the total mass of heavy nucleus, some mass is disappeared, this is mass defect and this mass appeared as the binding energy.
