A `400 kg` satellite is in a circular orbit of radius `2 R_(E)` around the Earth. How much energy is required to transfer it to a circular orbit of radius `4 R_(E)`? What are the changes in the kinetic and potential energies?
Given `g = 9.81 m^(-2) , R_(E) = 6.37 xx 10^(6) m`.

A

`-3.13xx10^3J,-6.25xx10^6J`

B

`3.13xx10^3J,-6.25xx10^9J`

C

`4.1xx10^4J,5xx10^10J`
