A) \[3v/4\]
B) \[6v\]
C) \[12v\]
D) \[3v/2\]
Correct Answer: B
Solution :
Orbital velocity of satellite \[v=\sqrt{\frac{GM}{r}}\] \[\Rightarrow \] \[\frac{{{v}_{A}}}{{{v}_{B}}}=\sqrt{\frac{{{r}_{B}}}{{{r}_{A}}}}=\sqrt{\frac{R}{4R}}=\frac{1}{2}\] \[\therefore \] \[\frac{{{v}_{A}}}{{{v}_{B}}}=\frac{3v}{{{v}_{B}}}=\frac{1}{2}\] \[\therefore \] \[{{v}_{B}}=6v\]You need to login to perform this action.
