Homework Equations
The Attempt at a Solution
Here's what I've thought.
See attachment 2. I think that the emitted electrons will follow trajectories which would intersect at a common point. The differently coloured trajectories shows different trajectories for emitted electrons.
I am having trouble making equations now. I just don't know where to start from.
The centrifugal force is balanced by the attractive force due to the electric field of cylinder. This is for the electron emitted exactly to the left.
[tex]\frac{mv_0^2}{r_0}=eE[/tex]
where E is the electric field due to long cylinder.
[tex]v_0^2=\frac{eEr_0}{m}[/tex]
This speed is same for all the emitted electrons as per the question.
Any help is appreciated. Thanks!
