A beam of electrons is accelerated through a potential difference of 10 kV before entering a region having uniform electric and magnetic fields that are perpendicular to each other and perpendicular to the direction in which the electron is moving. If the magnetic field in this region has a value of 0.010 T, what magnitude of the electric field is required if the particles are to be undeflected as they pass through the region?

A potential difference (p.d.) of 4800 V is applied between the cathode and anode of the tube. The cathode is heated and electrons are emitted from its surface. These electrons are then accelerated from rest and pass through a hole in the anode Cathode Anode Electrons 4800 V Show that the speed v of the electrons as they leave the anode is about 4 x 107 m s-1. V After leaving the anode, the electrons follow a parabolic path as...

As the electrons are accelerated through the second anode, the gain in kinetic energy is 2.0 x 10-15 J, and the speed of the electrons as they enter the region between the plates is 6.6 x 107 m/s. The electrons are moving to the right as they pass between the plates. The plates are 2.0 cm long, 1.0 mm apart, and as the electrons pass between the plates, the potential difference is 450 V. Determine the time it takes to...

In the diagram P1 and P2 are two parallel horizontal plates that
are 5.4 mm apart in a vacuum and have a potential difference of 189
volts maintained between them, the upper plate being positive.
Also, there is a horizontal magnetic field of 0.068. A horizontal
beam of electrons is directed between the plates so that it is
moving at right angles to the magnetic field as shown.

To create X-rays, a strong electric field is placed between an anode and a cathode. Electrons are then disconnected from the cathode and accelerated toward the anode. When they enter the anode, X-rays are created. In this case, the cathode is placed in x = 0, and the anode in x = 90 cm. The voltage between them is Uka 90 kV. You can assume that the electric field is homogeneous Determine the potential electrical energy of the electron W...

Finding the charge to mass (e/m) ratio of the electron Often in physics, we look for ways to find fundamental physical constants. From the set-up demonstrated in class, we are able to find a monumental combination of two physical constants-the charge of an electron (e) and the mass of an electron (m). Since the charge of an electron (e) is well known through other experiments, we will use the ratio of charge to mass to find the mass of an...

Problem 16. Find the maximum energy in eV of an x-ray photon produced by electrons accelerated through a potential difference of 50.0 kV in a CRT like the one show below. Metal target X rays High- voltage source Vacuum Electrons Heated filament Filament voltage X rays are produced when energetic electrons strike the copper anode of this cathode ray tube (CRT). Electrons (shown here as separate particles) interact individually with the material they strike, sometimes producing photons of EM radiation.

Electrons (mass m, charge –e) are accelerated from rest through a potential difference V and are then deflected by a magnetic field B that is perpendicular to their velocity. The radius of the resulting electron trajectory is:
