← ScienceUpon neutron absorption by uranium-235 causing fissile deformation, which mechanism initiates nuclear division?
A)Overcome strong nuclear force binding✓
B)Initial thermal bond disruption
C)Induced electromagnetic repulsion onset
D)Enhanced gravitational stress concentration
💡 Explanation
Fission initiates because the neutron absorption causes the uranium nucleus to deform; the strong nuclear force binding diminishes and the electromagnetic repulsion dominates, therefore the nucleus splits, rather than remaining stable under gravitation or heat distribution.
