Electrons are produced by heating a negatively charged metal plate (cathode) by thermionic emission in a cathode ray tube as shown below. They are accelerated to a positively charged plate (anode). 0n reaching the anode they collide with the atoms in the anode decelerating and releasing x-rays through a process called bremsstrahlung. 8 pts Assuming that the cathode and anode can be approximated as two parallel charged plates as shown below, +++++ + + + 1. Label the anode and cathode in the diagram above. Draw the electric eld lines between the plates. Draw the equipotential surfaces on the diagram. 2. If the voltage across the cathode-ray tube above is 20 kV, calculate the KE of the electrons as they reach the anode assuming they start from rest. The charge on an electron is Show the physics approach and formulae you used. (3 pts) l.an II. In eV 3. Calculate the speed of the electrons as they reach the anode. 4. What is the energy of the most energetic x-rays produced in this process (J or eV)
