1. The problem statement, all variables and given/known data A beam of electrons is fired into a rectangular region of space that contains a uniform magnetic field in the -z direction. The electrons are moving in the +x direction, as shown. The speed of the electrons in the beam is 6.00 × 106 m/s. The mass of an electron is me = 9.11 × 10−31 kg. The magnitude of the magnetic field in the rectangular region of space is 1.50 × 10−2 T. The rectangular region has a width d. What is the maximum value of d for which the electron beam will make it through to the other side of this rectangular region, and continue on to the right of the region? 2.

The attempt at a solution E=6.00 x 10^6m/s x 1.50 x 10^-2 T 90000 T x m/s Ok the problem I am having is relating distance to any equation I have. In previous problems I have worked, none of them had distance as part of the problem. If someone could just give me a hint or something about how to relate distance to the problem, that would be much appreciated.
