As we have learnt,

 

If two bodies of same material under identical environments -

\frac{(R_{c})_{1}}{(R_{c})_2}=\frac{A_{1}v_{2}}{A_{2}v_{1}}

-

 

 \\\frac{R_1}{R_2} = \frac{A_1}{T_1^4}{A_2T_2^4} = \left (\frac{r_1}{r_2}\right)^2\cdot \left (\frac{T_1}{T_2} \right )^4=\left (\frac{2}{}1 \right )^2\cdot \left(\frac{300}{600} \right )^4 = \frac{1}{4}
