DIRECTIONS : Each of the following questions contains two statements. Check if (A) Statement-1 is true, Statement-2 is true and Statement-2 is correct explanation of Statement-1. (B) Statement-1 is true, Statement-2 is true, but Statement-2 is not a correct explanation of Statement-1. (C) Statement-1 is true, but Statement-2 is false. (D) Statement-1 is false, but Statement-2 is true. Statement-1. Energy is released when heavy nuclei undergo fission or light nuclei undergo fuston. Statement-2. For heavy nuclei, binding energy per nucleon increases with increasing z, while for light nuclei, it decreases with increasing z (a) A (b) B (c) C (d) D

Nuclear fusion is the process by which two light nuclei combine to produce heavier, more stable nuclei.In this process, matter is not conserved because some of the material in the nuclei is converted into photons.This leads to the release of energy.Nuclear fission is the division of a heavy nucleus into two light nuclei.The fission process typically produces free neutrons and gamma photons and releases a lot of energy.In order for fission to produce energy, the total binding energy of the element produced must be less than the negative energy ( higher energy ) of the starting element.Nuclear binding energy is the energy needed to break down a nucleus into its components.For a heavy nucleus, the binding energy of each nucleon increases with the increase of the work. while for light nuclei it increases with increasing two statements and are true; and statement is the correct interpretation of the statement.The correct option is ( a ).
