i fail miserably at rearranging equations. how would i rearrange GM/r^2 = v^2/r to make M the subject?
this is to do with centripetal force, and the mass of a planet a space probe is orbiting
after working out the answer to v^2/r (which is 1.35ms^-2) I am left with GM/r^2 = 1.35ms^-2 i wasnt sure if it would be M = 1.35G/r^2...
as i said, i am terrible at rearrangements. any help would be appreciated
