## Homework Statement

Hi there! Could you please help me with this question? Am I doing it right?

A particle is moving under a force of the form F(r) = -Ar^3 (r-hat). The particle begins its movement at a distance r0 and velocity v0.

A. Find and draw the effective potential. Can the particle arrive at r=0?

B. Find the velocity v0 so that the particle will move in a circle.

C. What is the frequency of the small movements (w0) around that radius?
