An accelerating voltage of 2.54x10^3 V is applied to an electron gun, producing a beam of electrons originally traveling horizontally north in vacuum toward the center of a viewing screen 36.7 cm away.

(a) What is the magnitude of the deflection on the screen caused by the Earth's gravitational field? m

(b) What is the direction of the deflection on the screen caused by the Earth's gravitational field? up down east west

(c) What is the magnitude of the deflection on the screen caused by the vertical component of the Earth's magnetic field, taken as 20.0 µT down? mm

(d) What is the direction of the deflection on the screen caused by the vertical component of the Earth's magnetic field, taken as 20.0 µT down? north south east west

(e) Does an electron in this vertical magnetic field move as a projectile, with constant vector acceleration perpendicular to a constant northward component of velocity? Yes No (f) Is it a good approximation to assume it has this projectile motion? Yes No

A beam of electrons accelerated by a voltage V hits a target made of atoms of atomic number Z=20 . Suppose the atom ( Z=20) has a spherical and uniform distribution of outer electrons , so that Bohr's model can be used to describe its inner electron. An electron from the accelerated beam hits an atom of the target and ejects the innermost electron of the atom. Assuming that the electron of the beam transferred all its kinetic energy to...

(a) Calculate the wavelength of an electron under an acceleration voltage of (i) 200 V, (ii) 1.5 MeV and (ii) 2.5 GeV. Also, calculate the velocity of electrons moving at these acceleration voltages. How does this velocity compare to the speed of light. If they are comparable to the speed of light, use relativistic effects to calculate the wavelength of electron? (b) If the wavelengths are so small, can one expect the resolution of the TEM made with these energies...
