1-3 Show that the velocity with which electrons strike the target of an X-ray tube
depends only on the voltage between anode (target) and cathode and not on the
distance between them. [The force on a charge 6 (coulomhs) by a field E (voltsarn)
*41 Derive an expression for the absorption factor of a diffractorneter specimen in the form
of a flat plate of finite thickness I. (Note that the absorption factor now depends on 9).
