A) \[\frac{{{r}_{1}}}{{{r}_{2}}}\]
B) \[\frac{{{r}_{2}}}{{{r}_{1}}}\]
C) constant
D) \[{{\left( \frac{{{r}_{1}}}{{{r}_{2}}} \right)}^{2}}\]
Correct Answer: B
Solution :
As we know that, for the planet, the angular momentum is constant i.e. \[\Rightarrow \] L = constant \[m{{V}_{1}}{{r}_{1}}=m{{V}_{2}}{{r}_{2}}\] \[\Rightarrow \] \[\frac{{{V}_{1}}}{{{V}_{2}}}=\frac{{{r}_{2}}}{{{r}_{1}}}\]You need to login to perform this action.
