A 400 kg satellite is in a circular orbit of radius 
about the earth, where 
radius of the earth. With reference to the above situation, match the Column I (quantities) with Column II (calculated values)
Column I | Column II | ||
A. | Energy required to transfer it to a circular orbit of radius . | I. | |
B. | Change in Kinetic Energy) | II. | |
C. | Change in potential energy, | IIII. | |
D. | Total energy of satellite | IV. |
Choose the correct answer from the options given below.

Initially, energy of satellite 
Finally, energy of satellite, 
Change in total energy, 
Thus, 
The kinetic energy is reduced and change in KE is just negative of 
.
The change in potential energy is twice the change in the total energy namely,
The total energy of satellite 
Hence, 
.
