## Homework Statement

[PLAIN]http://img194.imageshack.us/img194/2062/57916122.png

## Homework Equations

[tex]F_{gravitational}= \frac{MmG}{r^2} [/tex]

[tex]F_{centrifugal}= \frac{mv^2}{r} [/tex]

## The Attempt at a Solution

I got this:

[tex]

dF_{centr} = dF_{grav} \longrightarrow \frac{dm \cdot v^2}{R+x} = \frac{MdmG}{(R+x)^2}

[/tex]

Is this correct?
