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 : |
\(\frac{3}{2}v\) \(\frac{3}{4}v\) 6 v 12 v |
6 v |
\(V ∝ \frac{1}{\sqrt{r}}\) \(\frac{v_1}{v_2} = \frac{\sqrt{r_2}}{\sqrt{r_1}}\) v2 = 2 v1 = 6 v |
