Homework Equations

The Attempt at a Solution

Is the particle moving under the influence of a single central force ?

Since the force always acts towards the center , work done by the force is zero . Energy is conserved . Potential energy at a particular radius can be found . But how do we find the kinetic energy of the particle ?

But how do we find the kinetic energy of the particle

The force from the potential field is the centripetal force that makes the object follow a circular path
