1. A particle with charge q and mass m travels into a region containing a uniform magnetic field B = 1 T. The path of the particle curves inside the region and exits travelling to the left at a distance of d = 2 m away from its entry point. The particle has a speed of v = 2 × 108 m/s when it enters the region containing the magnetic field.

T. The path of the particle curves inside the region and exits travelling to the left at a distance of d = 2
m away from its entry point. The particle has a speed of v = 2 × 108 m/s when it enters the region
containing the magnetic field.
a. Is the particle positively or negatively charged?
b. What is the magnitude of the ratio q/m?
c. If we would like the particle to maintain a straight path through the
region containing the magnetic field, we can add to that region a
uniform electric field. What direction and magnitude would be
necessary for this electric field?
d. Now consider that the boundary of the magnetic field region, shown
D
by the dashed line on the right, can have any shape. Redraw the boundary so that the final direction
of the particle is down. Redraw the boundary so the final direction is up. Redraw the boundary so that
the final direction is to the right.
