The energy required to shift the body revolving around a planet from `r` to `2r` is `E`. The energy required to shift it from `2r` to `4r` is (measured from centre of planet)

A small body is at a distance r from the centre of the mercury, where r is greater than the radius of the mercury. The energy required to shift the body from r to 2r measured from the centre is E . The energy required to shift it form 2r to 3r will be
