The radii of circular orbits of two satellites A and B of the earth, are 4R and R, respectively. If the speed of satellite A is 3 V, then the speed of satellite B will be :
-
- 3 V/4
- 6 V
- 12 V
- 3 V/2
Correct Option: B
Orbital velocity of a satellite in a circular orbit of radius a is given by
v = √GM / a
v ∝ √1 / a
