Solution
The correct option is C X is kinetic energy, Y is potential energy and Z is total energy.
Kinetic Energy of the Satellite =GMm2r
Potential Energy of the satellite =−GMmr
Total Energy of the Satellite =−GMm2r
Hence, Kinetic Energy Cure will be above 0 , hence X
Potential energy will be the lowest curve , hence Y
Total Energy is the curve is below 0 , but higher magnitude than Potential Energy . Hence , Z
Kinetic Energy of the Satellite =GMm2r
Potential Energy of the satellite =−GMmr
Total Energy of the Satellite =−GMm2r
Hence, Kinetic Energy Cure will be above 0 , hence X
Potential energy will be the lowest curve , hence Y
Total Energy is the curve is below 0 , but higher magnitude than Potential Energy . Hence , Z
