A satellite orbits the earth at a height of 500 km from its surface. Compute its (i) Kinetic energy, (ii) potential energy, and (iii) total energy. Mass of the satellite=300 kg, Mass of the earth=`6.0xx10^(24)`kg, radius of the earth=`6.4xx10^(6)`m, G=`6.67xx10^(-11)Nm^(2)Kg^(-2)`. Will your answer alter if the earth were to shrink suddenly to half its size?
