Suppose electrons in a TV tube are accelerated through a potential difference of 2.00 × 10 4 V from 1 answer below »

Suppose electrons in a TV tube are accelerated through a potential difference of 2.00 × 10⁴ V from the heated cathode(negative electrode), where they are produced, towards 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 (Chapter 26).

(b) What’s the magnitude of the electric field, if it is assumed constant?
