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