    The correct graph between the frequency n and square root of density (r) of a wire, keeping its length, radius and tension constant, is                      

    A)                                        

    B)                                        

    C)                                        

    D)                                 

    Correct Answer: C

    Solution :

                       We know frequency \[n=\frac{p}{2l}\sqrt{\frac{T}{\pi {{r}^{2}}\rho }}\]Þ \[n\propto \frac{1}{\sqrt{\rho }}\]            i.e., graph between n and \[\sqrt{\rho }\] will be hyperbola.
