                    In any fission process the ratio \[\frac{mass\,of\,fission\,products}{mass\,of\,parent\,nucleus}\,is\,:\]                                                

    A)                 less than 1          

    B)                 greater than 1

    C)                 equal to 1                                                           

    D)                 depends on the mass of parent nucleus

    Correct Answer: A

    Solution :

                                                              In fission process, when a parent nucleus breaks into daughter products, then some mass is lost in the form of energy. Thus, mass of fission products < mass of parent nucleus                         \[\Rightarrow \frac{Mass\,of\,fission\,products}{Mass\,of\,parent\,nucleus}<1\]                 Note:    1. Nuclear fission was discovered by Ottohan and Strassman.                 2. In each fission reaction a tremendous amount of energy \[(\approx \,190\,MeV)\] is released.
