1. The problem statement, all variables and given/known data What velocity does an electron need to have in order to travel straight through the crossed E and B fields, given that E = 1.0 x 105 N/C and B = 0.40 T? Answer: 2.5 x 105 m/s 2. Relevant equations E=F/Q F=BIl F=QvB 3. The attempt at a solution 1.0 x 105N/C / 1.6 x 10-19 = 6.25 x 1023N. I rearranged F=QvB - v=F/QB v = 6.25 x 1023N/ (1.6 x 10-19)(0.40T). I'm left with 9.765 x 1042 but I know this isn't my velocity but I'm confused on where to go or what I did wrong.
