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

Explanation

`5.9 xx 10^(9)` J
