Part A: What is the speed of a beam of electrons when the simultaneous influence of an electric field of 1.60×104 V/m and a magnetic field of 4.62×10−3 T, with both fields normal to the beam and to each other, produces no deflection of the electrons?
Part B: WHen the electric field is removed, what is the radius of the electron orbit?
Part C: What is the period of the orbit?

1) A mass spectrometer was used in the discovery of the
electron. In the velocity selector, the electric and magnetic
fields are set to only allow electrons with a specific velocity to
exit the fields. The electrons then enter an area with only a
magnetic field, where the electron beam is deflected in a circular
shape with a radius of 8.0 mm. In the velocity selector, E = 400.0

A beam of protons is moving in the +x direction with a
speed of 13 km/s through a region in which the electric field is
perpendicular to the magnetic field. The beam of protons is not
deflected in this region. The magnetic field has a magnitude of 0.8
T and points in the +y direction. Therefore, the magnitude
of the electric field is 11.570 V/m (= (13 x 10³ m/s) (0.8T)) and
the direction is along the negative z-axis.

A beam of electrons is shot from left to right (+x direction) at
a speed of 3 x 105 m/s through a pair of plates that are
3 cm apart and are uniformly charged. They produce a force of 4.8 x
10–17 N upward on the electron (+y
direction). So that our results are unambiguous,
vectors pointing from left to right will be called +x, and from
bottom to top (along the surface of the paper) will be
+y. Vectors...
