A) \[{{v}_{1}}={{v}_{2}}\]
B) \[{{v}_{1}}>{{v}_{2}}\]
C) \[{{v}_{1}}<{{v}_{2}}\]
D) \[\frac{{{v}_{1}}}{{{r}_{1}}}=\frac{{{v}_{2}}}{{{r}_{2}}}\]
Correct Answer: B
Solution :
Orbital velocity \[v=\sqrt{gr}\] \[\frac{{{v}_{1}}}{{{v}_{2}}}=\sqrt{\frac{{{r}_{1}}}{{{r}_{2}}}}\] As, \[{{r}_{1}}>{{r}_{2}}\] so, \[{{v}_{1}}>{{v}_{2}}.\]You need to login to perform this action.
