What is geostationary satellite ? For remain geo stationary obtain the equation of its height from the surface of earth.
Text Solution
Verified by Experts
`implies` If any earth.s satellite having orbital periodic time of 24 hours equal to the periodic time of rotation of the earth about its own axis and it appears always stationary as viewed from the earth and it revolve around the earth in the equatorial plane in east-west direction then such type of satellite is known as geostationary satellite. `implies` For this it is placed with suitable height (h) from the earth.s surface. `implies` If a satellite of mass m revolves at distance `r=R_(E)+h` from the centre of earth, height from the earth.s surface is as below. `h=((GM_(E)T^2)/(4pi^2))^(1/3)-R_E` T = 24 hour, then h = 35,800 km `implies` This satellite is widely used for telecommunication.
