Question

A heavy nucleus undergoing fission can release energy because the fission fragments generally lie:

G1 Physics · Accepted Answer

Very heavy nuclei have a smaller binding energy per nucleon than medium-mass nuclei. When a heavy nucleus splits into medium-mass fragments, the products move closer to the maximum of the BE/A curve. Therefore the products have greater total binding energy and lower total rest mass. The mass difference is released as energy. Correct option: B.
