An electron is travelling in the +ve x-direction of an inertial frame T. An acceleration is given to the electron in the +ve y-direction with as large as magnitude as possible.

How do I specify directions of the electric and magnetic fields that will achieve this?

Why are the choice of field directions unique?

Surely the elctric field is pointing in the -ve y direction but not sure about the magnetic field.

I'm not sure though. Also have no clue why it would be unique!

Hi cleggy! Welcome to PF! :smile:

I'm confused … is this two separate questions, a) for a purely electric field and b) for a purely magnetic field, or is it for one joint field? :confused:

If the former, then use the force! :biggrin:

(that's the Lorentz force, of course :wink:)​
