B) 1:4
C) 2:1
D) 1: 2
Correct Answer: B
Solution :
\[{{v}_{\operatorname{T}}}\propto {{\operatorname{r}}^{2}}\] \[{{v}_{{{\operatorname{T}}_{1}}}}=\operatorname{K}{{\operatorname{r}}^{2}}_{1}\] ?(1) \[{{v}_{{{\operatorname{T}}_{2}}}}=\operatorname{K}{{\operatorname{r}}^{2}}_{2}\] ?.(2) \[\frac{{{v}_{{{\operatorname{T}}_{1}}}}}{{{v}_{{{\operatorname{T}}_{2}}}}}=\frac{1}{4}\]
