Consider a beam of electrons that moves from the electron gun towards the screen of a cathode ray tube due to the potential difference of 15kV. A pair of coils are placed outside a cathode ray tube and produce a uniform magnetic field of 250 μT across the tube. Calculate the force experienced by the electrons if the magnetic field is in place: a. parallel with the direction of the beam. b. Perpendicular with the direction of the beam. c. 50 degrees with the direction of the beam.

Question
1. Consider a beam of electrons that moves from the electron gun towards the screen of a cathode ray tube
due to the potential difference of 15kV. A pair of coils are placed outside a cathode ray tube and produce a
uniform magnetic field of 250 μT across the tube. Calculate the force experienced by the electrons if the
magnetic field is in place:
a. parallel with the direction of the beam.
b.
Perpendicular with the direction of the beam.
50 degrees with the direction of the beam.
C.

Show your complete solution to each problem on a short bond paper.
Answers must be expressed in engineering notation (when the exponent of the base ten multiplier is not a
multiple of 3, press ENG or SHIFT+ENG, whichever the case.)
Example: 0.06N or 6.0x10² N must be expressed to 60x10³N or 60mN
