The electrons in the beam of a television tube have a kinetic energy of 2.37 × 10 ^-15 J. Initially, the electrons move horizontally from west to east. The vertical component of the earth's magnetic field points down, toward the surface of the earth, and has a magnitude of 2.73 × 10 ^-5 T. What is the acceleration of an electron due to this field component?

The electrons in the beam of a television tube have an energy of 13 keV. The tube is oriented so that the electrons move horizontally from north to south. The vertical component of the Earth's magnetic field at the location of the television has a magnitude of 42.0 ?T and is pointing down. a) In which direction does the force on the electrons act (enter N for north, S for South, E for East, or W for West)? Neglect a...

A beam of electrons with energy 250 MeV is elastically scattered through an angle of 10° by a heavy nucleus that is at rest. It is found that the differential cross-section is 65% of that expected for scattering from a point-nucleus. Estimate the root mean square radius of the nucleus. Neglect the recoil of the nucleus and use the rest mass of the electron as 0.511 MeV/c2.

In an experiment electrons are released with a kinetic energy of 2.8 eV. The amazing physicists doing the experiments are increasing the wavelength by 50%. Do you remember what happens? Are the photoelectrons faster or slower? The energy now is 0.44 eV. A) Based on that information, what is the material of the cathode? (calculate the work function and compare to table 28.1 in our textbook). B) What is the initial wavelength of the light? C) When you go a...
