    The graph between log R and log A where R is the nuclear radius and A is the mass number is

    A)                                  

    B)                          

    C)                                  

    D)                          

    Correct Answer: A

    Solution :

                       \[R={{R}_{0}}{{A}^{1/3}};\] where \[{{R}_{0}}=1.2\times {{10}^{-15}}m.\]                    Þ loge R = loge R0 +\[\frac{1}{3}{{\log }_{e}}A\]                    This is the equation of a straight line with positive slope.
