m_{1}v_{1}=m_{2}v_{2}

\therefore \frac{m_{1}}{m_{2}}=\frac{v_{2}}{v_{1}}= \frac{27}{8}

\therefore \frac{A_{1}}{A_{2}}= \frac{27}{8}

\therefore \frac{r_{1}}{r_{2}}= \frac{r_{0}A_{1}^{1/3}}{r_{0}A_{2}^{1/3}}=\left ( \frac{A_{1}}{A_{2}} \right )^{1/3}=\frac{3}{2}


Option 1)

8 : 27

Option 2)

4 : 9

Option 3)

3 : 2

Option 4)

2 : 3
