Ok, I'm not really interested in the final answer for this question, so much as how it is done and the reasoning behind the steps taken to get the answer:
Electrons are accelerated through a potential difference of 36.9V. The electrons then pass through a narrow slit to form a beam of electrons which passes into a region where there are perpindicular B and E. The E is produced by parallel plates 0.15m apart, and have a potential difference of 12v between them. What strength of B will cause undeflected passage of the electrons?
