A satellite is launched into a circular orbit of radius R around earth, while a second satellite is launched into a circular orbit of radius 1.02R. The percentage difference in the time periods of the two satellites is:

Two artificial satellites of masses  $m_1$ and $m_2$ are moving with speeds $v_1$ and $v_2$ in orbits of radii $r_1$ and $r_2$ , respectively. If r₁>r₂ then which of the following statements is true

Two planets A and B of equal mass are having their period of revolutions T_A and T_B such that T_A = 2T_B. These planets are revolving in the circular orbits or radii r_A and r_B respectively. Which out of the following would be the correct relationship of their orbits?

The time period of satellite in a circular orbit of radius R is T. The period of another satellite in a circular orbit of radius 9R is:
