A heavy nucleus having mass number 200 gets disintegrated into smaller fragments of mass number 80 and 120 . If binding energy per nucleon for parent atom is 6.5 eV and for daughter nuclei are 7 eV and 8 eV respectively and the energy released in the decay is given by X × 10 5 eV , then X will be

Correct answer

2200

Step-by-step solution

200 X → 80 Y + 120 Z 6.5 7 8 Energy released = 80 × 7 + 120 × 8 – 200 × 6.5 = 220 MeV = 2200 × 10 5 eV
