NEET Physics Nuclear Fission MCQ Question
In a nuclear fission reaction, such as the one where a uranium isotope 235 92 U is bombarded with a neutron, resulting in the fission products Ba and Kr, what is the role of the neutron in this process?
It acts as a catalyst without being consumed.
It initiates the fission by being absorbed by the uranium nucleus.
It provides the necessary energy for the fission to occur.
It stabilizes the fission products by absorbing excess energy.
Correct Answer
Detailed Explanation
The neutron is absorbed by the uranium nucleus, causing it to become unstable and undergo fission into smaller nuclei such as Ba and Kr, as described in the NCERT context.
