Question
A particle of charge Q = 6.0 μC and mass m = 1.0 x 10-10 kg is fired out of a
"charge gun" (essentially a capacitor with a hole in it) towards a uniform magnetic field pointing
into the page as shown in the drawing. The field has
a strength of B = 0.50 T. The particle enters the field
at point P, moving upward. The "charge gun" works
by accelerating the particle through a voltage AV =
200 V. You can ignore gravity for this problem.
a. How fast is the particle moving when it leaves
the charge gun?
b. Does the particle exit the magnetic field to the
left or right of point P? Make a sketch of its
path.
c. How far from point P does the particle exit the
magnetic field?
