Height of geostationary satellite is

A

16000 km

B

22000 km

C

28000 km

D

36000 km

Text Solution

Verified by Experts

The correct Answer is:
D
The principle of the geostationary satellite is its period of rotation is the same as that of the earth.
`(-GMm)/(r^(2))+m omega^(2)r=0`
i.e. `(GM)/((R+h)^(2))=((2pi)/(T))^(2)(R+h)`
h works out to 36000 km.
