Motion of planets and satellites

A satellite is launched into a circular orbit of radius R around the earth. A second satellite is launched into an orbit of radius (1.01)R. The period of the second satellite is larger than that of the first one by approximately


In the problem orbital radius is increased by 1%.
Time period of satellite Tr3/2  
Percentage change in time period 
32 (% change in orbital radius) =  32(1%)=1.5%
