satellite is in a circularExample 8.8 A 400 kgorbit of radius 2R, about the Earth. How muchenergy is required to transfer it to a circularorbit of radius 4R.? What are the changes inthe kinetic and potential energies ?

Answer»

Initially,Ei = - GMem/4Re

The change in T.E =gmRe/8

Substituting the values , we get=3.13*10^9

The K.E will be reduced and the P.E will become twice.
