The anode (positive terminal) of an X-ray tube is at a potential of +105000 V with respect to the cathode (negative terminal).
(a) How much work (in joules) is done by the electric force when an electron is accelerated from the cathode to the anode?
J
(b) If the electron is initially at rest, what kinetic energy does the electron have when it arrives at the anode?
