Homework Statement


Explain the circumstances that enable a particle to move un-deflected with uniform motion through an electric field if it is given an initial velocity perpendicular to the electric field. Assume the electric field is the only field present.[/B]

Homework Equations




The Attempt at a Solution


If the electric field was extremely weak and the particle had an extremely low charge.

Can you think of a property that the particle might have (or not have) that would allow it to move undeflected (even in a strong electric field)?

[EDIT: I think you're pretty close when you said "the particle had an extremely low charge". Why not go all the way? :woot:]

... it should be neutral right?
Yes, that would be one reason the particle doesn't deflect.

Now, the original statement of the problem asks for "circumstances". But I can't think of anything else. (I don't think mental telepathy telekinesis would be an acceptable answer.)
