An artificial satellite of the earth is to be established in the equatorial plane of the earth and to an observer at the equator it is required that the satellite will move eastward, completing one round trip per day. The distance of the satellite from the centre of the earth will be - ( The mass of the earth is `6.00 xx 10^(24)` kg and its angular velocity = `7. 30 xx 10^(-5) "rad"//"sec".`)
