An X-ray tube uses a 20,000 Volt difference to accelerate electrons across a 3cm gap between the plates of a parallel plate capacitor. The electrons pass through a hole in the second plate and impact on a tungsten target to create the X-rays.
A) what is the electric field in the gap between the plates?
B) What is the kinetic energy of the electrons in Joules when they impact the tungsten if they start from rest from the negative plate? The charge on an electron is -1.6x10^-19 C.
C) How fast are the electrons moving in s/s when they hit the tungten? THe mass of an electron is 9.3 x 10-31 kg.
