  • question_answer
    For a body moving with relativistic speed, if the velocity is doubled, then                                [Orissa JEE 2005]

    A)               Its linear momentum is doubled                              

    B)                          Its linear momentum will be less than double         

    C)                Its linear momentum will be more than double                  

    D)                Its linear momentum remains unchanged

    Correct Answer: C

    Solution :

                  Relativistic momentum \[=\frac{{{m}_{0}}v}{\sqrt{1-{{v}^{2}}/{{c}^{2}}}}\]          If velocity is doubled then the relativistic mass also increases. Thus value of linear momentum will be more than double.
