The Attempt at a Solution
Problem 1
>_> 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...
Problem 2
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.
