The area shown is the boundary of a magnetic field directed in the positive z direction. An electron with a velocity along the
x-axis enters the field at coordinates (x, y) =
(−2 m, 0) and exits 0.35 µs later at point A
whose coordinates are (x, y) = (0, 2 m).
What is the magnitude of B~
? The mass
of the electron is 9.109 × 10
kg and the
elemental charge is −1.602 × 10
Answer in units of µT
