Two satellites S1 and S2 are revolving in circular orbits around a planet with radius RI=3200 km and R2=800 km respectively. The ratio of speed of satellite S1 to the speed of satellite S2 in their respective orbits would be 1x where x=

Solution

Orbital velocity of a satellite in circular motion around a planet,

vo=GMR∝1R

Now, v1v2=R2R1=8003200=12

Hence, the value of x=2.
