If an electron is accelerated from 2 mm/s through a potential
difference of 500 V between two parallel plates separated by a
distance of 2.0 cm. What is the speed of the
electron?
An electron and a proton are each accelerated starting from
rest through a potential difference of 10
million volts. Find the momentum (in MeV/c) and the kinetic
energy (in MeV) of each, and compare with
the results of using the classical formulas.
An electron and a proton, starting from rest, are accelerated
through an electric potential difference of the same magnitude. In
the process, the electron acquires a speed ve, while the proton
acquires a speed vp. Find the ratio ve/vp.
An electron was accelerated through a potential difference of
1.00 ± 0.01 kV. What is the uncertainty of the position of the
electron along its line of flight?
An electron is accelerated through potential difference of 350V.
Electron enters magnetic field and moves in the circle with the
radius of 7.5cm.
a) What is the magnitude of the field?
b) What is the angular speed of electron?
c) What is the period of revolution of the electron?
2) A charge is accelerated from rest through a potential difference V and then enters a uniform magnetic field oriented perpendicular to its path. The field deflects the particle into a circular arc of radius R. If the accelerating potential is tripled to 3V, what will be the radius of the circular arc?
An electron is accelerated horizontally from rest by a potential
difference of 2100 V . It then passes between two horizontal plates
6.5 cm long and 1.3 cm apart that have a potential difference of
200 V
At what angle θ will the electron be traveling after it
passes between the plates?
Express your answer to two significant figures and include the
appropriate units.
An electron in the beam of a cathod-ray tube is accelerated by a
potential difference of 2.20 kV . Then it passes through a region
of transverse magnetic field, where it moves in a circular arc with
a radius of 0.185 m .
1) What is the magnitude of the field?
Express your answer with the appropriate units.
1. In a system design the electrons are accelerated from rest
through a potential difference of 250 V. The electrons travel along
a curved path because of the magnetic force exerted on them, and
the radius of the path is measured to be 5 cm long. If the magnetic
field is perpendicular to the beam what is the linear speed of the
electrons, what is the angular speed of the electrons and what is
the magnitude of the magnetic field...
Electrons in a cathode ray tube start from rest and are
accelerated through a potential difference of 11.6 kV. They are
moving in the +x-direction when they enter the space
between the plates of a parallel plate capacitor. There is a
potential difference of 320 V between the plates. The plates have
length 8.93 cm and are separated by 1.10 cm. The electron beam is
deflected in the negative y-direction by the electric
field between the plates.
