Consider following statements for fission of $\mathrm{U^{235}}$ with thermal neutrons.A. The % of nuclei undergoing unsymmetrical fission is maximum.B. In each fission, one thermal neutron is produced.C. Magnitude of energy released per fission is of the order 200 MeVCorrect statement(s) is/are:
(a)A and B
(b)B and C
(c)A and C
(d)C only
Answer
Answer: C ✓ checked by 4AB · confidence high
The source book printed B; on checking, C is correct — see the explanation.
Printed B; each fission gives about 2.5 neutrons.
Explanation
Thermal fission of ²³⁵U is predominantly asymmetric (mass peaks near 95 and 140) and releases ≈200 MeV, but it produces 2–3 neutrons per fission, not one. A and C.
