A force is given by Fx = Ax^(-3) (this is A times x to the power -3), where A= 8N.m^3.(adsbygoogle = window.adsbygoogle || []).push({});

a) For positive values of x, does the potential energy associated with the force increase or decrease with increasing x?

(I did imagine what would happen to a particle that is placed at rest at some point a and is then released. The professor concidered my answer wrong to be decreasing!)

b) Find the potential energy function U associated with the force such that U approches zero as x approaches infinity.

I didnt know how to answer b)

I thank you in advance for your help
