I made a picture because I'd struggle to get out a question without it. In the picture all things are constant except the strength of the magnetic field. It is at two different values. We see 2 cycloid paths of electrons that starts at rest. The circumference of the large path is exactly twice that of the smaller path. My question is, would the green path have the higher velocity away from the origin? Although both paths are equal in length, shouldn't the green path be the fastest? I base this conclusion on the amount of work the electric field does in both cases.
