A heavy nucleus having mass number 200 gets disintegrated into two small fragments of mass numbers 80 and 120. If binding energy per nucleon for parent atom is 6.5 MeV and for daughter nuclei is 7 MeV

Question

A heavy nucleus having mass number 200 gets disintegrated into two small fragments of mass numbers 80 and 120. If binding energy per nucleon for parent atom is 6.5 MeV and for daughter nuclei is 7 MeV and 8 MeV, respectively, then the energy released in the decay will be : (in MeV)

Answer:

220

Solution:

$E = (80 \times 7 + 120 \times 8) - 200 \times 6.5$

$= 560 + 960 - 1300 = 220$ MeV

Answer 220
