A) \[{{2}^{173}}:1\]
B) \[1\, :\, {{3}^{172}}\]
C) \[{{3}^{172}}:1\]
D) \[1: {{2}^{173}}\]
Correct Answer: D
Solution :
\[{{p}_{1}}={{p}_{2}}\] \[{{\operator name{m}}_{1}}{{v}_{1}}=\,\,{{m}_{2}}{{v}_{2}}\] \[2{{m}_{1}}={{m}_{2}}\] \[2\rho .\frac{4}{3}\pi R_{1}^{3}=\rho .\frac{4}{3}\pi R_{2}^{3};\,\,\frac{R_{1}^{3}}{R_{2}^{3}}=1\,\,:\,\,2;\,\,{{R}_{1}}:{{R}_{2}}=1:{{2}^{1/3}}\]
