1. The problem statement, all variables and given/known data An Electron is accelerated through a potential difference of 5.0KV (i) Find it's velocity. (ii) It is then passed through a region of transverse magnetic field where it moves in a circular path of radius 0.20m. Find the magnititude of the field. (iii) Find the time taken to for the electron to complete one rotation. 2. Relevant equations For (iii) Rotational KE = ½ Iw2 max velocity = 3x10^(7) Magnitude of the field = 8.52x10^(-4) potential difference = 5.0kV radius = 0.20m t = ? 3. The attempt at a solution (i) I got 3x10^(7) (ii) I got 8.52x10^(-4) (iii) I'm really not sure how to approach this question any hints in the right direction would be great.
