An artificial satellite orbits in a circular path. The height of the satellite from the surface of earth is 36,000 km. Such a satellite is called geo-stationary satellite. When the satellite is exactly vertically upwards the ground station, it sends a signal. How much time will the signal take to reach the ground station? The speed of signal is 3×108 ms-1.
