EXERCISE HINTS: GETTING STARTED I I’M STUCK! Suppose electrons in a TV tube are accelerated through a potential difference of 2.00 x 104 V from the heated cathode (negative electrode), where they are produced, toward the screen, which also serves as the anode (positive electrode), 25.0 cm away.
(a) At what speed would the electrons impact the phosphors on the screen? Assume they accelerate from rest, and ignore relativistic effects. What is the electric potential difference? How does it relate to the change in electric potential energy of a particle? How does it relate to the motion of a charged object in an electric field? m/s (b) What’s the magnitude of the electric field, if it is assumed constant? V/m Need Help? Read It Talk to a Tutor
