If all of the particles shown in the figure are electrons, what is the direction of the magnetic field that produced the indicated deflection?
Up (toward the top of the page)
Down (toward the bottom of the page)
Out of the plane of the paper
Into the plane of the paper
Which particle has the largest mass?
The Attempt at a Solution
>_> I am really not good at this right hand rule for forces thing. Anyways...I had my hand in a position that pointed into the the computer, but because the question is about electrons I was thinking the answer was
Out of the plane...
I was thinking...the bigger the mass, the bigger radius it would experience, and thus the answer was D. I just want to confirm my logic with this question.
