Hi,
I've been doing a Q where particles undergo circular/near-circular motion in an electric field. The electric field varies as 1/r. With the first particle, they set it off tangentially to the field lines, so it undergoes circular motion.
With the second particle, they set it off at a slight deviation from the tangential line. I figured, also from their diagram, the orbit would look slightly elliptical, perhaps still close to circular.
How do I go about deriving an equation of motion for this 'oblique incidence' particle? My only thoughts at this stage are that the force on the particle varies, since it's radial distance varies, unlike with circular motion.
What does it actually want me to do though?
Thanks!
