this reply was totally exciting to read. :)
you should both watch (if you haven't already) the history channel's, the universe series. i have it on on-demand and i absolutely lose myself in it. i think i understood that physicists think that based on current mathematic models, the only thing...
i totally can't even answer you on theta bc the diagram seems to be missing B fields.
B = magnetic field.
all i know is F = 0 when charges move parallel or antiparallel to the magnetic field bc sin0 = 0 and sin180 = 0
i hope someone helps...ill keep checking on this because i want to know...
ahhhhh...YAY! that's what i thought you were saying! :)
hehehe...you made me laugh bc i swear I am getting delerious just looking at it myself. i just learned how to use RHR when v and B exist on opposite planes, but geez, when they are in the same plane as in the picture...that just sucks for...
oh, but for part d...
F = q v B sin (theta)
rearrange for q, because you have F and v, and you, yourself found B :)
after you find q, you can do part e...
E = F/q
ok, to verify and solidify all of this.
Magnetic force, acceleration, and charge path all point in the same direction for positive charges only?
were my answers correct?
a) into page
b) out of page?
omg, don't kill me, but i don't get it. i know someone will though.
to verify, the velocity is pointing north, the magnetic Force is pointing left... the magnetic field for the 3Amp wire is +z, and magnetic field for the 1Amp wire is -z...?
ohhh! is that regardless of it being a positive or negative charge?
if that's true, then is the direction of the charge's path...
a) = into page
b) = out of page?
oh! i see what you're saying. i was told that the thumb would indicate the charge's movement...but ok. that works too. but I am not trying to get the direction of force. I am trying to get the direction of the charge's path. (?)
i think you meant thumb points in direction of charge. isn't my force the direction from my palm?
anyhow. i still can't get how to do this when v and b exist on the same plane as they do in my pic.
but lol...bc i am new to this, i can't say with certainty bc i kinda asked the SAME question a few threads below yours. i think magnetic FORCE would be pointing to the left for a proton, so it would be pointing to the right for an electron.
