A heavy nuleus having mass number `200` gets disintegrated into two small fragmnets of mass numbers `80` and `120`. If binding energy per nulceon for parent atom is `6.5 MeV` and for daughter nuceli is `7 MeV` and `8 MeV`, respectivley , then the energy released in the decay will be.

200 MeV

`-220 MeV`

220 MeV

180 MeV

Text Solution

Verified by Experts

The correct Answer is:

Energy released `=(80xx7+120xx8-200xx6.5) =220 MeV`
