Use the formula
r omega²= G M/r²
Period = 2pi/omega, This gives omega= 2 pi/(90*60) Now to find GM. We know
GM/Earth radius²= g, GM= earth radius²*g=ro²*g
r omega² = ro² g/r². Put r in terms of ro. This is r/ro =l
l³ ro= g /omega²,
l³r0=g*(90*60)²/4pi²=7238.6,
l³=1.13, l=1.04 . That means the distance of the satellite is
R=6645.3 km. please check the answer.
