A satellite orbits the earth at a height of `400km` above the surface. How much energy must be expanded to rocket the satellite out of the gravitational influence of earth? Mass of the satellite is `200kg,` mass of earth `=6.0 xx 10^(24) kg,` radius of earth `=6.4 xx 10^6 m`, `G=6.67xx10^(-11)Nm^2 kg^(-2).`
