A nucleus with mass number 240 breaks into two fragments each of mass number 120 , the binding energy per nucleon of unfragmented nuclei is 7 . 6 MeV while that of fragments is 8 . 5 MeV . The total gain in the binding energy in the process is :NEET 2021

TestHub · Accepted Answer

Given binding energy per nucleon of X , Y & Z are, 7 . 6 M eV , 8 . 5 M eV & 8 . 5 M eV respectively. ⇒ B . E . = ( 120 × 8 . 5 ) + ( 120 × 8 . 5 ) - 240 × 7 . 6 ⇒ B . E . = 2040 - 1824 = 216 M eV
