Two satellites S 1 and S 2 are revolving in circular orbits around a planet with radius R I = 3200   km and R 2 = 800   km respectively. The ratio of speed of satellite S 1 to the speed of satellite S 2 in their respective orbits would be 1 x where x =

Correct answer

2

Step-by-step solution

Orbital velocity of a satellite in circular motion around a planet, v o = G M R ∝ 1 R Now, v 1 v 2 = R 2 R 1 = 800 3200 = 1 2 Hence, the value of x = 2 .
