उत्तर १
Nuclear Fission :
When a slow neutron strikes `""_92U^235` nucleus, it is absorbed by the nucleus and an isotope `U^236` is formed. But `U^236`, is highly unstable, is immediately broken into two fragments and emits neutrons and energy. This fission can be represented by the following equation
उत्तर २
Nuclear fission:
`""_0^1n + ""_92^235U -> ""_56^144Ba + ""_36^89Kr + 3 ""_0^1n`

Calculate the height of the potential barrier for a head on collision of two deuterons.
(Hint: The height of the potential barrier is given by the Coulomb repulsion between the two deuterons when they just touch each other. Assume that they can be taken as hard spheres of radius 2.0 fm.)
