    The graph of In \[(R/{{R}_{0}})\] versus In A (R = radius of a nucleus and A = its mass number) is

    A)  a straight line

    B)  a parabola

    C)  an ellipse                    

    D)  None of the above

    Correct Answer: A

    Solution :

     \[R={{R}_{0}}{{A}^{1/3}}\] \[\Rightarrow \] \[\frac{R}{{{R}_{0}}}={{A}^{1/3}}\] \[\Rightarrow \]\[\ln \left( \frac{R}{{{R}_{0}}} \right)=\frac{1}{3}\ln A\] The above equation is of the form y = mx, which represents a straight line, passing through origin.
