A 400 KG SATELLITE IS IN A CIRCULAR ORBIT OF RADIUS 2Re ABOUT THE EARTH. HOW MUCH ENERGY IS REQUIRED TO TRANSFER IT TO A CIRCULAR ORBIT AF RADIUS 4Re ? what are the changes in the kinetic energy and potential energy
Initially, Ei = - GMem/4Re
Finally, Ef = - GMem/8Re
The change in T.E = Ef - Ei
=GMem/8Re = (GMe/Re^2)mRe/8
=gmRe/8
Substituting the values , we get : =3.13*10^9 J
The K.E will be reduced and the P.E will become twice.
