Correct Answer - C
Given `g=(2pi)/(omega_(1)+omega_(2))=(2pi)/((2pi)/(T_(1))+(2pi)/(T_(2)))`
`implies T_(1)=24h` for the earth
`impliesT_(2)=12h` (`T_(2)` being the time period of the satellite, it will remain the same as the distance from the centre of the earth remains constant)
`implies T=(2pi)/(omega_(2)+omega_(1))=(2pi)/((2pi)/(T_(1))-(2pi)/(T_(2))=24h`
