Vedclass · Answer

(C) The nuclear force acting between proton-neutron $(p-n)$,proton-proton $(p-p)$,and neutron-neutron $(n-n)$ are approximately equal and charge independent. Therefore,statement $A$ is wrong.The neutron reproduction factor $k$ (often denoted as $k$ instead of $A$) represents the ratio of neutrons produced in one generation to the number of neutrons in the preceding generation. If $k > 1$,the chain reaction is supercritical and the fission rate increases,meaning the reaction is in an accelerating state. Therefore,statement $B$ is correct.
