A geostationary satellite orbits the Earth at a height of nearly `36,000 km` from the surface of earth. What is the potential due to earth's gravity at the site of this satllite ? (Take the potential energy at infinity to be zero). Mass of the Earth `= 6.0 xx 10^(24) kg`, radius `= 6400 km, G = 6.67 xx 10^(-11) Nm^(2)//kg^(2)`.

Text Solution

Distance of satellite from the centre of earth=R=r+x
=6400+36000=42400km=`4.24xx10^(7)m`
