Question

Example 8.8 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 of radius 4RE?
What are the changes in the kinetic and
potential energies ?​

Answer 1

Answer:

Explanation:

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.
