Q1. Geostationary satellites are positioned at an upward distance of _________ km from the Earth's surface.
A 26000
B 36000 Correct
C 55690
D 45990
Explanation
A geostationary satellite appears fixed over one point on the equator because its orbital period matches the Earth's rotation. Such satellites are placed at about 36,000 km above the Earth's surface, more precisely around 35,786 km. A height of 26,000 km would not give the required 24-hour geostationary orbit. The values 55,690 km and 45,990 km are far beyond the standard geostationary altitude, so they would correspond to different orbital periods and would not remain fixed over the same ground point.
