Dear forum contributer,
The binding energy of a heavy nucleus is about 7 Mev per nucleon, whereas the binding energy of a medium-weight nucleus is about 8 Mev per nucleon. Therefore, the total kinetic energy liberated when a heavy nucleus undergoes symmetric fission is most nearly
(A) 1876 Mev
(B) 938 Mev
(C) 200 Mev
(D) 8 Mev
(E) 7 Mev
I found that this problem needs more info in order to be solved, I mean for example, if they said the heavy nucleus is Uranium of atomic weight 238, or something like that, I would have been able to calculate the energy liberated, by saying, the heavy nucleus will become medium nucleus by delivering 1 Mev per nucleon, so with 238 the energy liberated willl be around 200 Mev, which is the correct answer, but with only the given info, I would not be able to solve it
Many thanks
