Two satellites of masses m1 and m2 (m1 > m2) are revolving round the earth in circular orbits of radii r1 and r2 (r1 > r2) respectively. Which of the following statements is true regarding their speeds v1 and v2 ? |
v1 = v2 v1 < v2 v1 > v2 (v1/r1) = (v2/r2) |
v1 < v2 |
$v=\sqrt{\frac{G M}{r}}$ ; M = mass of earth $\Rightarrow \frac{v_1}{v_2}=\sqrt{\frac{r_2}{r_1}}<1$ |
