I know that the magnetic force is calculated via ##\underline{F} = q( \underline{v} \times \underline{B})##. Consider a particle with a velocity at some angle to a constant B field, both v and B in the same plane. Then the force will be acting in/out of the page depending on their orientation.
My question is: This particle will experience a net force perpendicular to the v vector throughout its entire motion, so the kinetic energy of the particle will not change. But since it is acted on my a net force, it will undergo an acceleration by NII. Is this acceleration simply calculated by F/m?
So this means that the acceleration vector will be parallel to the force vector. Is it really sensible to talk about the acceleration of the particle here? (It doesn't seem so since it is not actually accelerating - it's speed and velocity are constant throughout). I thought I could clarify this myself via google, but there appears to be contradictory views
Many thanks.
