1) What two sources of error are most likely to affect your
results?
2) Suppose protons were emitted rather than electrons. How would
this affect the experiment?
3) Compute the velocity of an electron that has been accelerated
through a difference of
potential of 100 volts. Express your answer in meters per
second.
4) Find the mass of the electron from your e/m and the accepted
value of the electron’s charge,
e=1.602x10 ^-19 C
Homework Answers
Please Specify which experiment you are talking about.
Question 3 can be answered however.
velocity of the electron is given by
v = [2eV/m]1/2
e = magnitude of electron charge = 1.6*10-19
m = mass of the electron = 9.1*10-31
V = accelerating voltage = 100 volts
v = 1.874 * 107 m/s

results?

Suppose that in an electron gun, electrons are emitted from a hot filament at point f and are accelerated by an electric field to an opening at o, as shown. The charge on an electron is (-e) where e = 1.6 times 10^-19 C. (a) If the voltage (same as electric potential) at point f is - 280 Volts, what is the potential energy of an electron at f? (b) The electrons come off the filament with very low velocity,...

013 (part 1 of 2) 10.0 points In an experiment designed to measure the strength of a uniform magnetic field produced by a set of coils, electrons are accelerated from rest through a potential difference of 323 V. The resulting electron beam travels in a circle with a radius of 6.96 cm. The charge on an electron is 1.60218 x 10-19 C and its mass is 9.10939 x 10-31 Assuming the magnetic field is perpendic- ular to the beam, find...

A. Introduction and Objective Every test has at least two sources of variation that affect the results of the test. The first source of variation is due to the experimental procedure, such as using two different testing machines that have different calibrations, or different observers reading the same equipment differently. This type of variation is often called the experimental error The second source of variation is inherent in the specimens (or sample population) themselves. In other words, no two specimens...

27B -- Experiment: Magnetic Force on a Moving Charge - qolme Objective: In this module you will observe the trajectory of an electron beam in a uniform magnetic field oriented in various ways to the electron velocity. You will then use your observation of the radius of the electron trajectory to measure the charge to mass ratio for an electron. Equipment: One elm apparatus (Lurge mounted glass bulb with Helmholtz coils); one Leybold or PASCO power supply for electron gun...

What do the positive helium ions do for the e / m apparatus? Choose the most complete, best answer. They help focus the electron beam and they emit photons which allow the beam to be seen. They help focus the electron beam. They emit photons which allow the beam to be seen. They get hot and glow. They are there so that the bulb does not implod They are there only when the electrons are not orbiting, otherwise, they move...
