    Two cars A and B move along a concentric circular path of radius \[\frac{{{v}_{A}}}{{{v}_{B}}}\] and \[\frac{{{r}_{B}}}{{{r}_{A}}}\] with velocities \[\frac{{{r}_{A}}}{{{r}_{B}}}\] and \[\frac{r_{A}^{2}}{R_{B}^{2}}\] maintaining constant distance, then \[\frac{R_{B}^{2}}{R_{A}^{2}}\] is equal to

    A)  \[3m/{{s}^{2}}\]                                             

    B)  \[-3m/{{s}^{2}}\]

    C)  \[0.3m/{{s}^{2}}\]                          

    D)  \[-0.3m/{{s}^{2}}\]

    Correct Answer: B

    Solution :

                    Velocity \[{{v}_{B}}\] Angular velocity co is constant. \[\frac{{{v}_{A}}}{{{v}_{B}}}\]                     \[\frac{{{r}_{B}}}{{{r}_{A}}}\] or            \[\frac{{{r}_{A}}}{{{r}_{B}}}\]
