1. The problem statement, all variables and given/known data Let E = 4 N/C in the x direction and B = 4 T in the -z direction. Let an electron move in the y-direction with speed 1m/s. What is the magnitude of the acceleration of the electron in m/s2? 2. Relevant equations Fm=qv X B Felectric field=qE F=ma 3. The attempt at a solution I plugged in values and found Fm to equal -6.408X10-19N and found Felectric field to also equal -6.408X10-19N. I'm not sure my sign is right on the first one because I was confused about the flow of the electron versus the flow of the current.... F=ma, and since I know the mass of an electron and I'm trying to find the acceleration, I think that I should add my two forces to get a total force, which equals ma. I did this and got a=4.508X10-7. I think this is wrong, though, because I think an acceleration would be larger than that.
