Energy is released in nuclear fission.
Total binding energy of the fission fragments is large than the total binding energy of the parent nucleus.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are truw but reason is not correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false.

Answer

A

Explanation

When a heavy nucleus splits two medium-size one,each of the new nuclei will have more binding energy per nucleon than the original nucleus.The extra energy will be given off e.g.if the uranium nucleus `""_(92)^(235)U`Is broken into two small nuclei,the binding energy difference per nucleon is about 0.8 MeV.The total energy given off is therefore.
`("0.8MeV")/("nucleon")xx235 "nucleon"=188 MeV`.
