A heavy nucleus P of mass number 240 and binding energy 7.6 MeV per nucleon splits in to two nuclei Q and R of mass numbers 110, 130 and binding energy per nucleon 8.5 MeV and 8.4 MeV, respectively. Calculate the energy released in the fission.

Text Solution

Verified by Experts

As per question total binding energy of heavy nucleus =`240xx7.6=1824` MeV
Total binding energy of nucleus Q =` 110 xx 8.5 = 935` MeV and total binding energy of nucleus R = `130 xx8.4 = 1092` MeV
`:.` Total binding energy of splitted nuclei Q and R = 935 + 1092 = 2027 Mev
`:.` Energy released in the fission = 2027 -1824 = 203 MeV
