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?

In the electron gun of an old TV picture tube, the electrons are accelerated by a voltage V . After leaving the electron gun, the electron beam travels a distance D to the screen; and in this region there is transverse magnetic field B and no electric field.

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 V/m and B = 4.7 x 10-4 T. The same value...

A beam of electrons traveling horizontally with an initial speed of vi = 3.0 x 107 m/s enters a uniform, vertically upward electric field with magnitude E = 2.0 x 104 N/C between the deflection plates of an oscilloscope, as shown in the figure. The initial velocity of the electrons is perpendicular to the field. The plates are d = 4.0 cm long. Ignoring all forces apart from the electrostatic interactions, calculate the magnitude and direction of the velocity of...

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. What...

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...
