An artificial satellite orbits in a circular path. The height of the satellite from the surface of earth is $36,000 \mathrm{km}$. 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 $3\times {10}^8 {\mathrm{ms}}^{-1}$.
