Under certain conditions the interaction between a "polar" molecule such as HCl located at the origin and an ion located along the x axis can be described by a potential energy U=−b[PLAIN]https://s3.lite.msu.edu/adm/jsMath/fonts/cmmi10/alpha/144/char3D.pngx^2, [Broken] where b is a constant.
What is Fx, the x component of the force on the ion?
What is Fy, the y component of the force on the ion?
The Attempt at a Solution
The y component of the force on the ion was fairly obvious but I am getting stuck on the x component.
I know that the force must me positive but it was incorrect when I tried +b[PLAIN]https://s3.lite.msu.edu/adm/jsMath/fonts/cmmi10/alpha/144/char3D.pngx^3[/B][/B] [Broken]
