Ok I really didn't real most of your post (2.30 AM really tired) but its basically the GPE of the higher orbit- the GPE of the lower orbit... both have an increase of 10 000 and have the same masses so when applied into -Gm1m2/r u get the same answer,,,
hmmm you sound paki,,, and seriously dude your having a public convo here,,, I dunno how I got onto your hit list but yeah,, I live very far away from you.. *recalls the meeting a stranger concept*
