Homework Statement
The boundary shown is that of a uniform magnetic field directed in the positive z direction. An electron enters the magnetic field with a velocity pointing along the x-axis and exits 0.63 μs later at point A. What is the magnitude of the magnetic field?
Homework Equations
F = qvb
v = s/t
r = mv/qb
The Attempt at a Solution
I calculated v = 2m/0.63 x 10^-6s = 3174603m/s. But I am stuck after this next step. I know that q = 1.6 x 10^-19C. Is my approach to the question starting out right? I am confused and paralyzed, unable to proceed forward. Thanks if anyone could offer some hints.
