thanks a lot.
i guess i will speak with my teacher about it tomorrow to get an explanation. my answer was the same as the one shown, minus the magnetic force downwards. would that be right?
EDIT: i showed the entire question btw
yeah i had two equal length electric force vectors (one to either side of the particle, towards the plates) and a gravity down. from what you said it sounds like I am right.
my problem is understanding if the particle is standing still. how do we know if it stands still? i assumed this when...
After looking at the question for a bit I realized that what made me not include the magnetic force on the fbd was because i think i am assuming that the particle is not moving, thus no magnetic force.
i think what i did wrong is related to the fact that i assumed the particle is not moving...
Hello all,
I just received back a unit test on fields that I wrote two or so months ago (teacher marks really slowly). I did pretty well on it. There is one question that I lost marks on. It isn't terribly difficult, but my teacher hasn't shown us the correct answers yet and I want to confirm...
