MCQ on Nuclear Fission and Nuclear Fusion: Nuclear fission is a nuclear reaction in which the nucleus of an atom is bombarded with low energy neutrons which split the nucleus into smaller nuclei. An abundant amount of energy is released in this process. Nuclear fission reactions are used in nuclear power reactors since it is easy to control and produces large amounts of energy.

Nuclear Fusion is a reaction that occurs when two atoms combine together to form one or more different atomic nuclei and subatomic particles like protons and neutrons. An enormous amount of energy is released in this process, much greater than the energy released during the nuclear fission reaction.

In this post we are providing you MCQ on Nuclear Fission and Nuclear Fusion, which will be beneficial for you in upcoming NEET, AIIMS, JEE, WBJEE, Medical and Engineering Exams.
