If the particle's velocity were perpendicular to the magnetic field, the magnetic force would be given by:
F = qvB
F is the magnetic force, q is the charge, v is the velocity, and B is the magnetic field strength.
Given values:
F = 0.320N
q = 7.3×10⁻⁶C
v = 4×10⁵m/s
Plug in the values and solve for B:
0.320 = (7.3×10⁻⁶)(4×10⁵)B
B = 0.110T
The magnetic force depends on the cross product between the particle's velocity vector v and the magnetic field vector B. If v and B are parallel then the cross product is 0. v points in the +x direction, therefore B must point in either the +x or -x direction.

A. </span>
No part of your vehicle will extend out into
the traffic lane.</span>
This kind of maneuver only shows your skill
to handle the vehicle in tight spaces, ability to judge distance, and showing control
of the vehicle as you turn into a straight-in parking space.
