Each of the electrons in the beam of a televisiontube has a kinetic energy of 15.0 keV. The tube is oriented so thatthe electrons move horizontally from north to south. The verticalcomponent of Earth's magnetic field points down and has a magnitudeof 45.0 μT. (Ignore the northward component of Earth'sfield.)
Part A:
In what direction will the electron beam deflect?
A) north
B) east
C) up
D) west
E) down
F) south
Part B:
Calculate the acceleration of a single electron due to the Earth'smagnetic field.
Part C:
How far will the beam deflect if it moves adistance of 20.0 cm to the south through the television tube?
