Q1. Electrons are accelerated through a voltage difference of
280 kV inside a high voltage accelerator tube. What is the final
kinetic energy of the electrons?
A. 2.80×105 eV
Q2.What is the speed of these electrons in terms of the speed of
the light? (Remember that the electrons will be relativistic.)

An evacuated tube uses a potential difference of ΔV =
0.58 kV to accelerate electrons, which then hit a copper plate and
produce X-rays.
Write an expression for the non-relativistic speed of these
electrons v in terms of e, ΔV, and m, assuming the
electrons start from rest.
Calculate the non-relativistic speed of these electrons
v in m/s.

Electrons are accelerated through a potential difference of 940
kV, so that their kinetic energy is 9.40×105 eV.
A) What is the ratio of the speed v of an electron having this
energy to the speed of light, c?
B) What would the speed be if it were computed from the
principles of classical mechanics?

In a color television tube, electrons are accelerated through a
potential difference of 15500 V. With what speed
do the electrons strike the screen? Give this speed in terms of the
speed of light. Hint: The kinetic energy of an electron which has
been accelerated through a potential difference of 1 V has a
kinetic energy equal to 1 eV. The Range of answers is
between 0.230 and 0.310c
I tried to use the conservation principle (1/2
mv2=qv), but that didn't get...

Electrons are accelerated through a potential difference of 3.59
kV in a cathode ray tube. Calculate the de Broglie wavelength of
the electrons.

At the 3-km-long Stanford Linear Accelerator, electrons are
accelerated to final kinetic energies of 47 GeV.
a. Electrons increase their kinetic energies approximately
uniformly every meter as observed in the laboratory frame. What is
the energy gain in MeV/m?
b. Suppose the classical KE expression was correct – how far
along the accelerator tube would the electrons need to travel
before they reached light speed?
c. OK, but that isn’t really what happens – even at 47 GeV of
kinetic...

For electron microscope which accelerates electrons from rest
through a potential difference of 10 kV.
(a) If the potential energy of an electron is taken to be 0
initially (at a 0 V plate), what potential energy does it have in
Joules after accelerating to the 10 kV plate? (The electrons
actually pass through a small hole in this plate before continuing
on toward the sample).
(b) What speed does the electron reach by the time it reaches
the 10...

Electrons are accelerated through a potential difference of 25
