## Homework Statement

## Homework Equations

All should be there, except taylor series, which is found here:

## The Attempt at a Solution

For part a, I got:

F(r)= [itex]\alpha[/itex](ke

^{2})((-r

_{0}/r

^{2})+(r

_{0}

^{n}/r

^{n+1}))

since force is the negative derivative of potential.

I'm pretty sure the answer to part b will involve a taylor expansion, but I'm not sure if the f(x) I use will be the equation I found in part a, or the derivative of the equation I found in part a. Additionally, I'm not sure how, in the answer we're supposed to get that's listed in the problem, they got (n-1) and the n term in the second part out of the exponent.

Thanks for any help!
