    Which of the following graphs shows the graph between velocity (v) and mass (m) when linear momentum (p) is constant?

    A)     

    B)       

    C)                        

    D)                       

    Correct Answer: C

    Solution :

    Linear momentum, \[P=mass(m)\times velocity(v)\] As P is constant \[\Rightarrow mv=\]constant or \[v\propto \frac{1}{m}\]
