  • question_answer
    A nucleus of  \[_{84}^{210}Po\] originally at rest emits a particle with speed v. What will be the recoil speed of the daughter nucleus                                                             [DCE 2002]

    A)            4v/206                                    

    B)            4v/214

    C)            v/206                                       

    D)            v/214

    Correct Answer: A

    Solution :

                       \[_{84}P{{o}^{210}}{{\to }_{82}}{{X}^{206}}{{+}_{2}}H{{e}^{4}}\] Using conservation of linear moments \[206\,{v}'+4v=0\Rightarrow {v}'=-\frac{4v}{(206)}\]\[\Rightarrow \,|{v}'|\,=\frac{4v}{206}\]
