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. |
