(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Potential energy function is given by U = C/x, where C is a positive constant.

a. Find the force as a function of x.

b. Is this force directed toward the origin or away from it?

c. Does the potential energy increase or decrease as x increases?

d. Answer b, and c if C is a negative constant.

2. Relevant equations

How do you relate U = C/x to force?

3. The attempt at a solution

I tried the formulas.

F = mg

U = mgy

But I am not sure how you relate both of them together
