Consider three models of the Mass distribution in the Milky Way

[QUOTE="Bandersnatch, post: 6619685, member: 399360"] This is not the correct approach. You've introduced some extra masses here, that I can't see the reason for. You will only really have one mass to deal with here - the mass attracting the point particle to the centre of the galaxy. The mass of the orbiting particle will cancel out when you compare the gravitational force with the centripetal force. Note, you were on the right track with the first four lines in your first attempt at solution in the opening post - with the exception of incorrectly stating the equation for the centripetal force. Take heart, the whole exercise involves relatively simple calculations, once you see what's going on.But let's take it one step at a time. Question a) for model 1. Can you first state an example of a function f(x) that is constant for all x? Don't jump to subsequent points until we've sorted this one out first. (FYI the forum supports LaTeX, if that's something you're comfortable writing equations in) [/QUOTE]
